Lightly pound chicken breasts to tenderize for more even cooking. Season both sides with all-purpose seasoning or a blend of salt, black pepper, garlic powder, onion powder, and paprika.

Heat oil over medium-high heat in a large skillet. Cook chicken breasts for 7–9 minutes per side or until the internal temperature reaches 160°F (71°C). Add 1 tablespoon of unsalted butter to the skillet toward the end of cooking. Transfer chicken to a plate to rest.

Reduce heat to medium. Add remaining unsalted butter to the pan. Once melted, add sliced bell peppers and onion. Season vegetables with all-purpose seasoning, using approximately 1 teaspoon. Sauté until vegetables are tender and deeply colored, about 5–7 minutes. Reduce heat to low.

Slice or dice the cooked chicken. Return chicken to the skillet with the vegetables. Stir to combine and turn off the heat.

Cover the chicken and vegetable mixture with provolone cheese slices. Place a lid on the skillet and let cheese melt, approximately 3–5 minutes.

Toast hoagie rolls if desired. Spread garlic aioli or mayonnaise onto both sides of each roll. Evenly divide the chicken, pepper, onion, and cheese mixture among the rolls.
