Fill a large pot with lightly salted water and bring to a boil. Stir in penne and return to a boil. Cook pasta uncovered, stirring occasionally, until cooked through but still firm to the bite, about 11 minutes; drain.
Heat oil in a large skillet over medium heat. Cook and stir peppers until slightly tender, about 7 minutes. Stir in onions and cook until onions soften and turn golden, 7 minutes. Add garlic and cook 5 minutes, stirring occasionally.
Stir sausage slices into onions and peppers, reduce heat to medium-low, cover, and simmer for 10 minutes.
Stir drained penne into sausage and onions and reduce heat to low. Season with garlic and herb seasoning, sea salt, and pepper to taste.
