Marinara Meatballs Sliders w/ Mozzarella

1/2-1 bag of Italian flavored croutons, crushed completely
½-1 yellow or white onion, diced finely
2 cloves garlic, minced finely
1-2 lb ground beef
salt and pepper to taste
1 egg plus ½ cup water
slider buns, or sub buns
mozzarella or provolone cheese slices (or grated Parmesan)
1-2 large jars of your favorite marinara sauce (sweeter flavor tastes good)

Combine ground beef with crushed croutons, onion, salt, pepper, egg and water.  Form balls and brown in a skillet on at least two sides.  Meatballs don’t need to be cooked through, just brown nicely.  Add meatballs to the crockpot/Instapot when browned and cover with the marinara sauce and cook on low 4-8 hours (or pressure cook for 20 minutes or so).  Place cheese on buns and spoon the meatball and marinara sauce over it.  Enjoy!!!  It will be messy- eat with a fork if you like.

*For a healthy alternative, serve hot meatballs over freshly grated zucchini for “noodles”.
