Mix yogurt, salt, black pepper, and cumin in a small bowl.
Place bread on a flat surface. Remove the crust, then flatten bread with a rolling pin. Spread each slice with yogurt mixture. Add a slice of turkey to each.
Finely chop banana peppers, sprinkle onto each slice of bread. Slice bell pepper thinly. Finely dice 1-2 slices to add to banana peppers and reserve the remaining slices for an extra side veggie.
Drain and rinse corn; add a few kernels on top of each slice of turkey. Roll each tightly and slice in half. If needed, place a toothpick through each roll to keep in place.
Serve with sliced strawberries on the side.
