2 boneless, skinless chicken breasts
3 tablespoons prepared poultry spice rub
2 tablespoons olive oil
1 large yellow onion
1 large green apple (Granny Smith or similar)
4 wooden skewers
1 sweet baguette
Honey mustard, to taste

1. Prepare chicken: Cut each breast into 8 large chunks, to get a total of 16 chicken pieces. Coat each piece evenly with spice rub, cover, and refrigerate for at least two hours.
2. Soak skewers in water for at least one hour.
3. Preheat grill to 375°F (a medium-hot fire) or preheat oven to 425°F.
4. Slice onion into 16 large, wedge-shaped chunks that are big enough to be skewered.
5. Core apple and cut into 12 slices.
6. Remove chicken from fridge and coat evenly with olive oil.
7. On each skewer, spear 4 pieces of chicken, 3 slices of apple, and 4 pieces of onion, alternating ingredients.
8. Place skewers on the grill, and cook until chicken is just cooked through and slightly charred, turning often, about 8 minutes. Or, arrange skewers on a rimmed baking sheet and bake until chicken is just cooked through, about 10 minutes.
9. Meanwhile, slice the baguette into four quarters, then slice each quarter in half horizontally.
10. To make each sandwich, spread a bit of mustard onto the bottom half of baguette, then arrange the ingredients from one kabob on the bread. Top with remaining baguette half.

Makes 4 sandwiches.
