Toss the tomatoes in olive oil, half the minced garlic, salt and pepper. Roast at 450 for 10-15 minutes until the tomatoes begin to brown.
While that’s cooking, cook pasta according to package instructions until al dente. Drain and toss with olive oil; set aside.
In the same pot you used to cook the pasta, add 1 tbsp olive oil and 1 clove minced garlic. Heat over medium heat 1 minute. Add half and half, milk and Colby cheese. Stir until cheese is melted. Turn off heat and add pasta into the mixture. Toss to coat. Add diced mozzarella and sprinkle generously with pepper and a little bit of salt.
Add roasted tomatoes, chopped mozzarella and basil. Serve and enjoy!
