Modified from Robin Miller
1 cup all-purpose flour
2 teaspoons garlic powder
2 teaspoons onion powder [I didn't have onion powder, so I combined the onion powder and salt and used 4 tsp of onion salt]
2 teaspoons mustard powder
2 teaspoons dried oregano
2 teaspoons dried thyme
2 teaspoons salt
1 teaspoon ground black pepper
12 (5-ounce) skinless, boneless chicken breast halves
cooking spray
Preheat oven to 400 degrees F.
Put all the spices in a large bowl and then dredge each breast in it, shaking off excess coating.
Transfer chicken to baking sheet and spray with olive oil cooking spray. Bake 25 to 30 minutes, until chicken is golden brown and cooked through.
Serves 4 with leftovers for other dishes.
