Cook the cheese tortellini according to package instructions. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the zucchini, yellow squash, and red bell pepper. Sauté for about 5-7 minutes until the vegetables are tender.
Add the cherry tomatoes and minced garlic to the skillet. Cook for an additional 2-3 minutes until the tomatoes start to soften.
Stir in the cooked tortellini, dried basil, dried oregano, salt, and pepper. Toss everything together until well combined and heated through.
Remove from heat and sprinkle with grated Parmesan cheese. Toss gently to combine.
Serve warm, garnished with fresh basil leaves if desired.
