Open-Face Philly-Style Chicken Sandwiches

Preheat broiler. Heat oil in a large skillet over medium-high heat. Add chicken; cook and stir about 5 minutes or until no longer pink. Reduce heat to medium. Add onion, pepper strips, garlic, Italian seasoning, and ground pepper. Cook and stir for 5 to 8 minutes or until the vegetables are tender. Reduce the heat to low. Place cheese slices in a single layer over the chicken mixture. Cover and cook about 1 minute more or until the cheese melts.

Meanwhile, arrange bread slices on a baking sheet. Broil the bread 4 to 5 inches from the heat for 1 to 2 minutes per side or until toasted. Using a spatula, transfer portions of cheese-topped chicken mixture onto the toasted bread slices.
