In a large pot of boiling salted water, cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet over medium heat, heat the olive oil. Add the diced chicken breasts, season with salt, pepper, oregano, and basil. Cook until the chicken is lightly browned and cooked through, about 6-8 minutes.
Add minced garlic to the skillet and sauté for about 1 minute until fragrant. Then, stir in the cherry tomatoes and cook until they start to soften, around 2-3 minutes.
Add the cooked pasta to the skillet, tossing everything together. Gently fold in the mozzarella balls until they are slightly melted and integrated into the dish.
Taste the pasta and adjust seasoning with more salt and pepper if needed. For extra creaminess, you can mix in grated Parmesan cheese.
Remove from heat, and garnish with freshly chopped basil before plating.
Notes
Serve with a drizzle of olive oil and extra fresh basil for garnish.
