Directions

1. Preheat oven to 400° F. Spray an 8" x 8" x 2" baking dish with non-stick cooking spray; set aside.
2. Place the asparagus and tomatoes onto a large baking sheet. Drizzle with olive oil, season with 1/2 teaspoon salt and 1/4 teaspoon black pepper, toss to coat.

Using a fork, slightly smash tomatoes, releasing their juices; set aside.

Whisk in the milk and cook until mixture thickens, approximately 4 to 5 minutes. Stir in the mozzarella cheese and 2 ounces of the Asiago cheese, stir until cheese melts into the sauce. Add in the pasta, asparagus, tomatoes with juices, olives, remaining 1/2 teaspoon salt and remaining 1/4 teaspoon black pepper, mix to fully combine. Remove from heat, stir in the feta cheese.
