Cook the penne pasta in a large pot of salted boiling water according to package instructions. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.
Add the chopped sun-dried tomatoes and cook for another 2 minutes, stirring occasionally.
Add the sliced chicken tenderloins to the skillet, sprinkle with salt and paprika, and cook until the chicken is no longer pink, about 5-7 minutes.
Reduce the heat to low, pour in the half and half (or cream and milk), and stir well. Allow it to simmer for a few minutes.
Stir in the shredded mozzarella cheese until melted and the sauce is creamy.
Add the cooked penne pasta to the skillet, tossing to coat evenly in the sauce.
Season with red pepper flakes to taste and garnish with fresh basil before serving.
