Preheat the oven to 350. Toss the torn bread and olive oil on a parchment-lined baking sheet; season well with salt and pepper. Bake for 30 minutes occasionally tossing the croutons to keep them from burning. Let cool completely.
In a large bowl toss the snap peas, avocado, feta, herbs, and toasted bread with the basil vinaigrette, season with salt, and freshly cracked pepper. Serve, or allow the salad to sit for about half an hour for the flavors to blend.
Notes
Storage: This salad does not keep particularly well for later because the croutons will continue to absorb dressing over time and turn to mush. If you plan on having leftovers, reserve the croutons for later.
