You can practically feel the sunshine on your back when you take a bite of this spaghetti squash dish, which is inspired by the bright flavors of the Mediterranean. You’ll start by simmering plump, briny Castelvetrano olives in extra-virgin olive oil. In go the shrimp and plenty of salt and pepper, followed by cooked spaghetti squash, fresh basil, and a generous squeeze of lemon juice. Toss until everything is coated in an irresistible lemon-basil sauce, then finish it off with crumbled feta and red pepper flakes.
