Rinse the yellow squash under cool water and slice into 1/4-inch thick rounds. Drain on a towel to remove excess moisture.

In a mixing bowl, combine all-purpose flour, cornmeal, salt, pepper, and garlic powder. Mix well to create a dry batter.

Beat an egg in a separate bowl for dipping. Heat oil in a frying pan to 350°F.

Dip each slice in the beaten egg, then dredge in the flour mixture, coating well on all sides.

Fry the coated squash slices in hot oil for 2-3 minutes on each side until golden brown.

Remove fried squash and drain on paper towels. Sprinkle with salt while hot.
