Mix together ingredients for meatballs (eggs, breadcrumbs, onion, orange pepper, garlic diced, ground beef, salt, pepper). Using an ice cream scoop, portion out equal-sized meatballs, either 1" or 2". Smaller meatballs are better for serving on toothpicks.

Bake or pan fry meatballs. To bake them, arrange meatballs on a baking tray so they don't touch. Bake meatballs 20 minutes at 375. To pan fry them, heat 1 tbsp olive oil in a large frying pan on medium. Add meatballs, stirring regularly to brown all sides. The meatballs don't have to be fully cooked inside since they'll finish cooking in the crock pot.
While meatballs are cooking, make the pineapple BBQ sauce. Mix together crushed pineapple and BBQ sauce.
Place partially cooked meatballs in the crock pot and pour the sauce on top. Cook 4 hours on high, stirring occasionally to redistribute the sauce. Serve on rolls, on rice, or with toothpicks for an appetizer.
