Mix all ingredients. Pat into muffin tins. Bake at 350 °F for approximately 30 minutes.
Notes
These freeze really well, and 1 'meat muffin' is a good sized portion for a toddler. Because they're in a muffin tin, they end up softer than meatballs, which I think is good for toddlers starting out on meats.
Substitutions
Gluten: Gluten is a protein found in specific grains (wheat, spelt, kamut, barley, rye). Other grains are naturally gluten-free but may have cross-contact with gluten-containing grains. Look for certified gluten-free products if you need to avoid gluten. Find out more about wheat and gluten substitutions.
