Can also be made as stuffed spaghetti squash. Just wash the squash without peeling it, cut it in half, and remove the seeds. Fill both halves with a mixture of tomatoes, onion, sour cream, tuna, and olive oil. And sprinkle with gruyère cheese to brown it. Very fun! This squash really makes spaghetti, which amuses children and adults who don't like traditional squash. More enjoyable to eat than regular squash.
