This is a great make-ahead recipe that you can even freeze in advance. We keep it simple, but feel free to make it your own with additional seasonings, vegetables, or even dairy-free cheese. If using a cheese alternative, I recommend sprinkling it on top of the meat mixture, under the tots.
All-Veggie Option: For a vegan option without a meat alternative, heat 1 tablespoon oil in a skillet over medium heat. Add the onion and saute until softened, 5 to 10 minutes. And increase the vegetable mixture in the recipe to 4 to 5 cups.
