These rich sandwiches drip with juicy seasoned chicken, ripe tomato, and briny pickles. If you don’t have a sandwich press or Panini grill, cook them on a stovetop grill, griddle, hot skillet, or charcoal grill with chunks of sweet bell pepper and onion.
Heat oil in a large skillet over medium-high heat. Add chicken, cumin, garlic powder, salt, and pepper; cook and stir 6 to 8 minutes or until no longer pink in center. Remove from heat.
Spread 4 slices of bread with mustard. Layer with chicken, ham, pickle, cheese, tomato, and onion. Top with remaining 4 slices of bread. Lightly brush both sides with remaining 1 tablespoon oil.
Heat a sandwich press or stovetop grill pan. Place sandwiches in press; cook about 10 minutes or until golden and cheese is melted.
