Shrimp Scampi with Angel Hair Pasta

Preheat oven to 400 degrees F (200 degrees C).

Prepare a baking sheet with cooking spray.

Arrange tomato halves onto prepared baking sheet.

Drizzle olive oil over the tomatoes; season with salt and pepper.

Roast tomatoes in preheated oven until edges are crisp, about 35 minutes.

Transfer to a cutting board to cool; cut into small chunks.

Bring a large pot of lightly salted water to a boil.

Cook angel hair in the boiling water, stirring occasionally until cooked through but firm to the bite, 4 to 5 minutes; drain.

Transfer to a large bowl.

Melt butter in a skillet over low heat.

Cook and stir onion, garlic, and half the basil in the hot butter until the onion is translucent, about 5 minutes.

Stir shrimp, tomato chunks, mushrooms, and garlic powder into the onion mixture.

Increase heat to medium-low and cook and stir until shrimp are bright pink on the outside and the meat is no longer transparent in the center, about 6 minutes.

Pour shrimp mixture over the angel hair pasta; top with Parmesan cheese and lemon juice and toss to coat pasta completely.

Garnish with remaining basil.
