Mushrooms and Eggs
In pais Vasco—Basque country—many tapas are substantial and filling. This meets that requirement, but it is also quick and simple. I once had it made with chanterelles, which of course produced a sublime version. If you can get them, or other wild mushrooms, the dish will be really special, but it’s quite wonderful with shiitakes. As for an omelet, you can put most anything you want in here; especially good is about a cup of chopped shrimp added just before the eggs. You can serve this on toast or bread, as is often done in tapas bars, or just by itself. It also makes a fine main course for two.
