Prepare the gluten-free mashed potatoes if you do not already have them on hand. Keep them warm.
Preheat the air fryer to 400°F (200°C). Lightly spray the basket with oil and arrange the frozen chicken tenders in a single layer.
Air fry the chicken tenders for 6–8 minutes, or according to the package directions, until crisp and fully cooked. Chop them into bite-sized pieces.
For an oven method, cook the chicken tenders according to the package directions, then cut them into pieces.
Cook the turkey ham until lightly crisp and heated through. Chop or crumble it into small pieces.
Heat the drained corn until warm.
To assemble the Loaded Mashed Potato Bowls, spoon about 1 cup of mashed potatoes into each bowl.
Sprinkle cheddar cheese over the warm potatoes so it begins to melt.
Add the crispy chicken pieces, warm corn, turkey ham, and diced green onions.
Finish each bowl with a dollop of sour cream and serve warm.
