Haricots verts are thin, tender green beans. If you can't find them, use trimmed regular green beans, but add them to the pasta after 8 minutes of cooking since they'll take longer to cook. You can make the salad ahead, but dress it just before serving so the beans don't turn drab.
For tortilla soup like abuela used to make, start with zesty garlic chicken, add tomato sauce, and kick up the flavor when you top with avocado, cheese and cilantro.
