These are my new favorite way to make meatball subs! CJ is using biscuits to make these awesome mini meatball sub sandwiches. What are you adding to these subs? What you'll need: -Can of biscuits. -Meatballs. -Red sauce. -Sliced provalone cheese. -Pizza seasoning. How to make them: Flaten out the biscuits. Add a spoonful of sauce to each biscuit. Put a couple meatballs on each biscuit. Add slices of cheese to each. Spinkle on some seasoning to each sub, Throw into a 375f oven for 15-20 minutes.
