Preheat an oven to 400ºF and mix the seasoning blend in a bowl. Set aside.
Cut the potatoes and peppers and place in a large bowl. If your baby potatoes are on the larger side, quarter instead of half. Toss with 2 Tbsp of olive oil before coating in 1/2 the seasoning blend. Bake the veggies on a large baking sheet for 10 minutes while you prep the chicken.
Toss the diced chicken breast in oil before coating in 1/2 the seasoning blend.
Once prepped, push the veggies to the sides of the baking sheet, creating space for the chicken in the center. You can also use a separate baking sheet.
Bake for 16-20 minutes until the chicken reaches an internal temp of 165oF. Serve with fresh cilantro and lime wedges.
