Ingredients

  

Po Boy Chicken Marinade

  • 1/4 cup orange juice fresh
  • 2 tsp orange zest
  • 1 tsp ground ginger
  • 1/4 cup white balsamic vinegar
  • 2 tbsp spicy pepper medley seasoning
  • 1 tsp thyme leaves
  • 1/2 cup canola oil

Grilled Chicken Po Boy Sandwich

  • 2 lb chicken tenders
  • 8 French sandwich buns 6″, sliced lengthwise (or gluten-free bread if desired)
  • 8 romaine lettuce leaves
  • 16 slices tomato
  • 3 tbsp green onions sliced

Spicy Avocado Mustard Sauce

  • 2 tsp grainy mustard
  • 1 cup prepared guacamole
  • 2 tsp orange juice fresh
  • 1 tsp orange zest
  • 2 tbsp spicy pepper medley seasoning
  • 1/2 tsp crushed red pepper

Instructions

 

  • Make the chicken marinade: whisk together orange juice, orange zest, ground ginger, white balsamic vinegar, spicy pepper medley seasoning, thyme and canola oil until combined. Reserve 1/4 cup (50 mL) of the marinade to brush on the chicken while grilling.
  • Place chicken tenders in a large resealable bag or shallow dish and pour the remaining marinade over them. Turn to coat, then refrigerate for at least 30 minutes; longer marinating time intensifies the flavor.
  • While the chicken marinates, make the spicy avocado-mustard sauce: in a bowl combine grainy mustard, prepared guacamole, orange juice, orange zest, spicy pepper medley seasoning and crushed red pepper. Stir until smooth, cover and refrigerate until ready to use.
  • When ready to cook, remove the chicken from the marinade and discard any leftover marinade. Grill the chicken over medium-high heat for 4 to 5 minutes, or until cooked through, brushing with the reserved marinade during the last few minutes of grilling.
  • To assemble, spread the avocado-mustard sauce on the split French buns. Layer each with romaine lettuce, tomato slices and grilled chicken. Finish with sliced green onions and serve immediately.
