Preheat oven to 350 degrees. Spray regular sized muffin tin or use foil liners. Recipe makes 12 regular muffins filled all the way to the top or 24 mini muffins. Chop turkey and spinach or use food processor. I prefer larger pieces so I use a knife. Separate egg whites into bowl saving egg yolks for Cheesy Bacon Egg Muffins(for DH and kids) Mix all ingredients together and pour into muffin tin. Bake at least 20 minutes at 350 degrees for moist squishy muffins or up to 30 minutes for a dryer more solid texture.
