Cook the Pasta: Boil a large pot of salted water and cook the pasta according to package instructions until al dente. Drain and set aside.
Cook the Chicken Bites: In a large skillet, heat olive oil over medium-high heat. Add the chicken bites, seasoning with salt, pepper, and Italian seasoning. Cook until golden brown and cooked through, about 6-8 minutes. Remove the chicken from the skillet and set aside.
Make the Garlic Butter Sauce: In the same skillet, reduce the heat to medium and add the butter. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant. Return the cooked chicken to the skillet and toss to coat in the garlic butter sauce.
