In mixing bowl, combine ground beef, egg, bread crumbs, finely chopped red onion and finely chopped garlic. Scoop into regular size (or mini size) muffin tins, filling about 2/3-3/4 full. Press your finger into each meat muffin to create a small "well" for the BBQ sauce. Add a "blop" (about 1 tsp) of BBQ sauce to each muffin...regular size and mini!
Bake mini meatloaves and meatloaf bites at 350 for 30-35 minutes, or until no longer pink in the middle. Remove from muffin tin and place on plate.
Saute green beans in skillet with olive oil for 4-6 minutes, or cooked to your preferred "crunchiness" or "softness." Stir often! Season with salt and pepper to taste.
Make garlic toast in toaster or toaster oven.
Serve BBQ Mini Meatloaves and/or Meatloaf Bites with Sauteed Green Beans and Garlic Toast.
