Preheat the oven to 350°F (175°C)
Dice the potatoes and onions, then divide them evenly among 5 meal prep containers.
Drizzle the diced potatoes and onions with olive oil and sprinkle with BBQ seasoning to taste.
Season the chicken pieces with BBQ seasoning, then add about 4 oz of chicken to each meal prep container
Pour approximately 2 tablespoons of BBQ sauce over each container, ensuring that everything is well coated.
Sprinkle 1/4 cup of shredded cheddar cheese over each container for that gooey, cheesy goodness.
Place the meal prep containers in the preheated oven and bake for 40 minutes, or until the chicken is cooked through and the potatoes are tender.
Once out of the oven, top each meal prep bowl with an extra drizzle of BBQ sauce for added flavor.
