Ingredients

  • 1 pound Chicken Tenderloins (cut into bite‑size pieces; can substitute chicken breast)
  • 0.5 piece Red Bell Pepper (sliced thin)
  • 0.5 piece Green Bell Pepper (sliced thin)
  • 0.5 piece Yellow Bell Pepper (sliced thin)
  • 0.5 cup Red Onion (sliced; about 1/4 medium onion)
  • 2.5 tablespoons Olive Oil (extra‑virgin preferred)
  • 0.75 teaspoons Salt (adjust to taste)
  • 0.5 teaspoons Black Pepper (freshly ground preferred)
  • 1 teaspoon Chili Powder (mild smoky flavor)
  • 2 teaspoons Smoked Paprika (adds deep smoky flavor)
  • 0.25 teaspoon Cayenne Pepper (adjust for heat level)
  • 1 tablespoon Minced Garlic (fresh minced; can substitute 1 tsp garlic powder)

Instructions

  1. Preheat Oven

    Set the oven to 425°F (220°C) and let it preheat while you prepare the ingredients.

    Time: PT5M

    Temperature: 425°F

  2. Prep Chicken and Veggies

    Slice the red, green, and yellow bell peppers into thin strips, slice the red onion, and cut the chicken tenderloins into bite‑size pieces.

    Time: PT10M

  3. Season and Toss

    In a large mixing bowl combine the chicken, peppers, and onion. Drizzle with olive oil, then add salt, black pepper, chili powder, smoked paprika, cayenne pepper, and minced garlic. Toss everything together until evenly coated.

    Time: PT5M

  4. Arrange on Sheet Pan

    Spread the seasoned mixture in a single layer on a sheet pan (line with parchment paper if desired) so the pieces aren’t crowded.

    Time: PT2M

    Time: PT30M
