Slash carbs by swapping pizza crust for spaghetti squash, which shreds into noodle-like strands after baking.
Preheat oven to 400°F.
Coat cut sides of 1 halved spaghetti squash (seeds removed) with olive oil and sprinkle with salt and pepper.
Place halves cut-side down on a baking sheet coated with cooking spray.
Bake 30 to 35 minutes; cool 5 minutes.
Keeping squash on the baking sheet, use a fork to gently shred the inside of the squash into spaghetti-style strands.
Stir 1⁄2 tsp garlic powder into each half.
Top with 1⁄4 cup jarred pizza sauce.
Sprinkle each with 1⁄2 cup shredded mozzarella cheese and top with tomato slices from 1 Roma tomato.
Turn the oven to broil.
Return spaghetti squash halves on the baking sheet to oven, and broil on LOW 5 to 10 minutes, or until cheese begins to brown.
Remove from oven; top each with 1⁄2 cup chopped basil.
