Zucchini Grinders

1. Preheat the oven to 375 degrees F.

2. Pour oil into a skillet over medium heat. Add onion, zucchini, and garlic and cook until veggies become slightly tender. Season with red pepper flakes.

3. Lay out 4 squares of foil that are large enough to wrap up one of the sub rolls. Put a roll onto each square of foil. Spoon the zucchini mixture into each roll until full. Spread a layer of marinara sauce (or diced tomatoes) onto the zucchini mixture. Top with a handful of shredded mozzarella. Wrap the rolls in foil, making sure that they’re completely closed. Place wrapped rolls on a baking sheet.

4. Bake for 15 minutes in the preheated oven, until bread is heated through, and cheese is melted.
