Wash and thoroughly dry the strawberries, then chop them into small, even pieces and set aside.
Peel the bananas and add them to a large bowl. Mash well with a fork until smooth and well-mashed. Then, add the eggs, Greek yogurt, milk, and vanilla extract to the bowl. Whisk until combined, then mix in the sugar.
Set aside 1 tablespoon of the flour for the strawberries. In a separate bowl, whisk together the remaining flour, baking powder, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Don’t over-mix.
Add the chopped strawberries to a small bowl with the reserved tablespoon of flour and gently toss to coat.
Set aside 1/4 cup of the strawberries, then fold the remaining strawberries into the batter.
Line a muffin pan with liners or lightly spray a nonstick or silicone muffin pan. Evenly divide the batter between the cups, filling each about 3/4 full.
Top the muffins with the remaining 1/4 cup of strawberries. Bake at 350°F for 23-25 minutes, or until a toothpick inserted in the center comes out clean. Let cool, then enjoy.
