Sandwiching meaty black sea bass fillets together with an aromatic filling of red onion and fresh oregano perfumes the fish as it roasts. It tastes—and looks—wonderful topped with a colorful salad of small tomatoes, olives, and more oregano. The peppery, lemony herb, native to the Mediterranean, is a natural with fish.

Talk about a sandwich with bravado: The bold flavors start with the smear of green-olive-flecked oil on the chewy, rustic rolls. Then come the layers of juicy sausages, piquant arugula, and piquillos. The fire-roasted sweet red peppers from Spain are well worth seeking out for their tenderness and subtle, smoky heat.

Two of summer's tastiest offerings help you spoon up more of the skin-saving antioxidant lycopene.

Potatoes are a cornerstone of the Peruvian diet, and for good reason: They have been cultivated in the Andes for more than 8,000 years, and the country boasts a whopping 3,000 varieties of the tuber, which comes in a myriad of shapes, colors, and sizes. In the regional capital of Huancayo, creamy, gently spiced cheese sauce is usually poured over the potatoes or served as a dip. To really highlight the potatoes (purple-fleshed ones look especially dramatic), we serve them over the sauce, with accompaniments of lime and meaty olives.

Comfort food, Peruvian style. The chile sauce's brilliant yellow hue comes from a pinch of turmeric, as well as bottled ají amarillo paste, which also lends a fruity heat. It is thickened with bread and walnuts (a tasty trick for stretching foods to feed many mouths) and blended to a satiny smoothness. Although Peruvian cooks usually shred the chicken and add it directly to the sauce, we like the elegance of serving the roast chicken breasts on top of the sauce and passing extra around in a gravy boat.

The Sicilian-style tomato sauce has tons of Mediterranean flavor, thanks to the orange peel, olives, and oregano.

"Ingredients are considered 'spices' in Algerian cooking," says Zadi, and this slaw illustrates his point, with olives contributing saltiness, carrots and sun-dried tomatoes adding sweetness, and fennel and parsley lending an incredible freshness. In the dead of winter, when vegetables are scarce, the clean flavors of this salad are as close as you're likely to get to a summertime farmers market.

No need to call your local pizza joint. Thanks to prepared dough and bottled roasted red peppers, making your own calzones can be easy and far more satisfying.

Boneless top round roast is a cut taken from the flavorful leg. Here, we sliced it across the grain into steaks that are grilled and served with a Mediterranean-inspired combination of artichoke hearts, olives, and fire-roasted tomatoes.

An easy marinade of garlic, lemon, thyme, and a dollop of the North African hot sauce harissa make these green olives memorable. If you can, prepare the olives ahead—they improve with age.

This C-food salad supplies the full RDA of infection-fighting vitamin C, which also helps you absorb iron from the octopus.

The bright flavor helps balance the richness of the other fillings.

It is said that France is divided into three regions of gastronomy determined by the fat it uses for cooking. In the north, this is butter. In the southeast, olive oil. In the southwest, it is unquestionably duck fat.

_Editor's note: This recipe is from chef Wolfgang Puck. The tapenade can be served as an hors d'oeuvre, in a small bowl, surrounded with tiny toasted bread slices or crackers. At Spago, we spread goat cheese onto lightly toasted croutons, top them with the tapenade, and serve them with our Caesar Salad._

Chimichurri, the traditional accompaniment for steak in Argentina, is an olive oil-based sauce with vinegar, parsley, and other seasonings. In Argentina, cattle are grass-fed, and the vinegary relish complements the herbal beef beautifully. The meat is very lean, so it's best rare.

Chicken cacciatore is a ubiquitous dish in Italian-American restaurants, but we think it is even more delicious when made with veal shoulder roast. Slowly braising the meat in a heady tomato sauce enriched with pancetta, olives, and porcini produces a dish so good, you'll find yourself sneaking nibbles all the way to the table. It's even better the next day—if you can contain yourself.

In this rustic marriage of land and sea, red-pepper flakes add just the right amount of heat to hearty potatoes and wonderfully tender octopus (from a can!)

Oltranti and his family prepare this dish with rabbit, but it's equally appealing with chicken. Roasted with super-savory pancetta and olives, the garlicky meat stays moist in a shallow bath of white wine.

Start making the dough one day in advance; it needs to be refrigerated overnight.
