Gently fold in chopped spinach and crumbled feta cheese.
Spoon the muffin batter into the prepared muffin pan, filling each cup about ¾ full.

Nutrition information is an estimate and will depend on your specific ingredients.
Mix the almond flour, cornmeal, baking powder, baking soda, and salt thoroughly. This ensures even distribution of leavening agents and seasonings throughout the batter.
When adding wet ingredients to dry ingredients, mix until just combined. Overmixing can result in tough muffins. It's okay if there are a few lumps in the batter.
Make sure to grease your muffin tin or use muffin liners to prevent the muffins from sticking. You can use cooking spray or a little oil or butter for greasing.
Quick tip:Fresh spinach works best in this recipe, adding a vibrant green color and fresh flavor. If you use frozen spinach, please thaw it thoroughly and squeeze out any excess moisture before adding it to the batter.
