    This is on my standard rotation for easy, quick dinners on hectic days! It comes together quickly & my kids love helping me out by ripping up the biscuit dough. I like to press in chopped garlic or garlic powder into the dough so it’s like garlic bread. If you’re vegetarian, swapping out meatballs for veggie ones works beautifully! I like adding some chopped onions and peppers into mine to boost the veggies. It’s a perfect, versatile recipe that’s easy on the budget & will please even the pickiest eaters in your life! Thanks for another winner Julia!
