Preheat oven to 400 degrees.

Line a baking sheet with parchment paper, foil, or spray with oil

Add the bread to a food processor or the bottom of a blender. Pulse until bread crumbs are formed. Remove and set aside.

Add to that same food processor or blender, the bell pepper, onion garlic, cauliflower (steamed and squeezed), parsley, salt, and pepper. Pulse until pretty smooth. Chunks are fine if you don't mind! I knew my kids were more likely to love them if they weren't too chunky.

In a large bowl, combine both meats with the egg.  Pour the blended mixture over it, add bread crumbs and mix until combined. ( I prefer to use my hands.)

Using a 1 oz cookie scoop, scoop mixture and line up meatballs on the pan.  They can be pretty close but not touching. No need to roll them by hand unless you want them to be a more perfect ball. I let the bottoms stay flat.

Bake for 18-20 minutes. Don't be too scared if they ooze how poultry does in the oven!

Now they're ready to eat right out of the oven, OR my preferred method is to give them a quick pan-fry before dinner to add some texture and browning to the outside.
