Wash the yellow squash and slice it into rounds about 1/4 inch thick.

In a bowl, mix the flour, salt, and black pepper. Dredge each squash slice in the flour mixture until well coated.

Heat the vegetable oil in a frying pan over medium heat. Once hot, add the coated squash slices in batches, frying until golden brown on both sides, about 3-4 minutes per side.

Remove the fried squash from the pan and place them on paper towels to drain excess oil. Serve hot.
