This verdant pasta salad signals a fantastic start to spring with a shower of fresh herbs. Mini shell pasta and peas are a perfect pair—the pasta serves as a kind of catcher’s mitt for the sweet, bright green peas. You could also use orecchiette, an ear-shaped pasta that serves the same purpose. Skip the chicken and add 1/4 cup crumbled feta or goat cheese for a vegetarian main, or try 2 slices of cooked, crumbled bacon for meat lovers. If you have a nut allergy but still want some crunch, try toasted coarse breadcrumbs or sunflower seed kernels.
