Preheat oven to 350 F. Spray a 9x 13" baking dish with pan spray of choice, set aside.
In a large pan, brown chopped chicken breast in olive oil. Season with a little salt and pepper.
Once chicken is browned on all sides, add onion and garlic. Continue cooking until onion starts to go soft and translucent.
Add broccoli, smoked paprika, and mustard powder. Continue cooking until broccoli turns brighter green and starts to soften a little.
Stir in cheese soup, making sure to evenly coat everything. Taste, season with salt, pepper, and/or additional smoked paprika or mustard powder if desired.
Pour mixture into a 9 x 13 casserole dish or baking pan.
Sprinkle shredded cheese over mixture.
Arrange tater tots in a single layer on top of the cheese.
Bake for about 1 hour, or until the tots are golden and crispy.
Serve hot!
