Preheat oven to 425 degrees.
In a small bowl, combine all seasonings.
Cut chicken breasts into 1-inch pieces.
Arrange chicken in a 13 x 9 inch baking dish and sprinkle with the seasoning mix.
Drizzle ONE tablespoon olive oil over the chicken and toss to coat on all sides.
Dot the chicken with the butter pieces.
Bake chicken in the preheated oven for 16-18 minutes, or until cooked through. Halfway through cooking time stir the chicken bites. For crispier chicken bites, turn the broiler on high for the last 2 minutes of cooking until golden brown.
Remove the baking dish from the oven, and let rest for 5 minutes before serving.
