Preheat oven to 350 degrees F and prep a muffin tin with nonstick spray.
In a large bowl, whisk together the eggs, milk, pepper, garlic powder, and salt.
Distribute the egg mixture among 6 muffin molds. Evenly top with chopped spinach, tomatoes, and chicken. Bake for 25-30 minutes until it's puffy and looks set in the middle.
Remove the pan from the oven and transfer to a wire rack for a few moments. To remove the egg muffins, run a sharp knife along the edges to loosen the sides, and carefully nudge them out.
