Chop the chicken, broccoli, and potatoes into bite-sized pieces, all around the same size. Combine them in a large mixing bowl.
Next, make the marinade: combine all the ingredients (cilantro through cayenne pepper) in a food processor or blender and process until fully combined.
Pour the marinade over the chicken and veggies - toss until all the pieces are evenly coated.
Transfer the ingredients to a large baking pan. Pop it in the oven for 35-40 minutes, until the chicken and potatoes are cooked through, but the chicken is not overcooked.
Serve warm with fresh tomatoes, chopped cilantro, and paleo ranch dressing!
