Preheat your griddle or skillet over medium heat.
Add olive oil to coat the surface.
In a bowl, mix paprika, garlic powder, dried oregano, salt, black pepper, and onion powder.
Rub this spice mixture over both sides of the chicken breasts.
Place the seasoned chicken on the griddle.
Cook each side for about 5-7 minutes or until fully cooked.
While the chicken is cooking, toast the Texas toast on the griddle with a light coating of butter.
Let each side turn a golden brown.
When the chicken is nearly done, place American cheese slices on each breast to melt.
Layer the chicken and cheese between the toasted bread slices.
Serve immediately.
