This is my version of an undersung regional Mexican dish that’s deeply satisfying yet remarkably light. In Spanish it’s called caldo de queso, featuring chunks of potato simmered in tomato-tinted broth until soft, with fresh cheese such as queso fresco added to each bowl. The cheese mostly keeps its shape but softens and begins to break apart. I like adding whatever vegetables happen to be in season, such as poblano chiles, summer squash, and tomatoes.

Milk is usually added to this style of soup, making a creamier broth that serves as a bridge between the cheese and all the vegetables. But you can also leave the dairy out for a brighter tasting broth. Chicken stock is traditionally used in caldo de queso and it's what I prefer for its richness, but vegetable broth will work, too, for an even lighter soup. Unlike most traditional versions, I add vinegar, fresh tomatoes, and lots of fresh oregano to balance the soft, rich cubes of queso fresco.
