Spicy Mustard Grilled Chicken Po’ Boy Sandwich Recipe

If you’ve visited New Orleans, you know a classic po’ boy when you taste one. This grilled chicken po’ boy delivers the same bold, comforting flavors with a lighter, protein-packed twist. Instead of frying, the chicken is marinated and grilled for a smoky, tangy result that pairs perfectly with a creamy, spicy avocado-mustard sauce.

Heat + tang + smoke = crave-worthy flavor. The sandwich is built on a French-style sub roll, layered with crisp lettuce, juicy tomato and sliced green onions, then finished with the zesty avocado mustard. For a gluten-free option, swap in your favorite gluten-free bread.

Ingredients

  

Po Boy Chicken Marinade

  • 1/4 cup fresh orange juice
  • 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)
  • 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 fresh orange juice
  • 1 tsp orange zest
  • 2 tbsp spicy pepper medley seasoning
  • 1/2 tsp crushed red pepper

Instructions

 

  • Make the marinade: whisk together orange juice, orange zest, ground ginger, white balsamic vinegar, spicy pepper seasoning, thyme and canola oil until combined. Reserve 1/4 cup (50 mL) of the marinade to brush on the chicken while grilling.
  • Marinate the chicken: place chicken tenders in a large resealable bag or glass dish. Pour the remaining marinade over the chicken, turning to coat. Refrigerate for at least 30 minutes, or longer for more flavor.
  • Prepare the sauce: in a bowl combine grainy mustard, prepared guacamole, orange juice, orange zest, spicy pepper seasoning and crushed red pepper. Stir until smooth. Cover and refrigerate until ready to assemble the sandwiches.
  • Grill the chicken: remove chicken from the marinade and discard any leftover marinade. Grill over medium-high heat 4 to 5 minutes, or until cooked through, brushing with the reserved marinade during the last few minutes.
  • Assemble the sandwiches: spread avocado mustard sauce on the French rolls, add romaine, tomato slices and grilled chicken. Sprinkle with sliced green onions and serve immediately.

Notes

To make this gluten-free, choose gluten-free rolls or bread. For extra heat, increase the crushed red pepper to taste.
