Preheat oven to 350 degrees. Spray a 12-cup muffin tin with nonstick spray and set aside.
Place oatmeal in a food processor and process oatmeal into a course flour. Add baking powder, soda and flaxseed, and pulse to combine. Add the yogurt, eggs, honey, vanilla and bananas and process until everything is blended and you have a smooth batter.
Remove the blade from the food processor and stir strawberries into the batter.
Divide batter equally between 12 muffin cups in prepared muffin tin. Bake 18-20 minutes, until a toothpick inserted into the center of a muffin comes out clean.
Cool in pan 10 minutes then gently transfer to a wire rack to finish cooling.
