This vegan meatball sub sandwich is super hearty, super flavourful and chock-full of veggies. Baked lentil and mushroom meatballs smothered in marinara sauce and served up in a crusty bun stuffed with spinach, onion and peppers. You might need a knife and fork to get these bad boys in your mouth!
All the pepperoni pizza yumminess in a make ahead slider form! The gooey insides are perfect with the cheesy garlic butter topping! I always keep the ingredients on hand to make these! | Little Dairy on the Prairie
