Preheat oven to 205 degrees celcius or 400 degrees f
Using magic bullet or blender, blend the garlic, onion and bell pepper together.
Then in a mixing bowl, add the ground meat, blended mix from 1st step, bread crumbs, parmesan cheese, egg and seasonings and mix well.
Using an ice cream scoop, scoop out balls of the mixed meat, and then push a 1x1cm mozarella cube into the center of the meatball. Make sure the cheese is completely covered.
Place each meatball in baking dish.
Once all of the balls have been made, place in oven for 10 minutes
Remove dish from oven, and then pour over the pasta sauce and cover everything with the grated/shredded cheese. Return to oven for remaining 10 minutes. It may sometimes take longer for the cheese to melt. I would recommend a total of 20-25 minutes (10 with just the meatballs, and then 10-15 with pasta sauce and cheese top).Warning!! For those on a diet, don't add cheese over the pasta sauce. The extra cheese makes it a very heavy dish. A leaner version is to just add the pasta sauce (make sure to cover each meatball with sauce) and then stick back in oven. Serve warm/hot over spagetti and enjoy.
