Preheat oven to 425°F (218°C).
Line a medium sheet pan with parchment paper.
Place chicken thighs on the sheet pan and season generously with cayenne, Italian seasoning, garlic powder, onion powder, salt, and pepper.
Bake for 35–40 minutes, or until the chicken is fully cooked and the edges are crisp.
While the chicken bakes, prep the sandwich toppings:
Slice avocado, cucumber, and tomato.
Toast the sourdough bread.
Make hummus if you're going the homemade route.
Once the chicken is done, build your sandwich:
Spread hummus (or BBQ sauce) on toasted sourdough.
Layer with avocado, cucumber, tomato, roasted chicken, and sprouts.
Sprinkle with a little extra salt and pepper, if desired.
Enjoy fresh!
