Preheat oven to 375F and spray a 9-inch pie dish or similar oven-safe baking dish with cooking spray; set aside.
Slice thawed tater tots in half or place a large pile on cutting board and roughly chop them; retain some size and texture and don't chop them too small.
Transfer tater tots to a large mixing bowl. Add the meat or protein option, sour cream, add 1 cup cheese, seasoning blend, salt, pepper, and stir to combine.
Transfer mixture to prepared baking dish, smoothing the top lightly with a spatula. Top with remaining 1 cup cheese.
Bake for 30 to 35 minutes, or until top is bubbly and golden browned. Serve immediately with crackers, bread, pita chips or pita bread, tortilla chips, dip tater tots into it, or just eat it with a spoon.
Notes
Storage: Store leftover dip in an airtight container and refrigerate for up to 3 days. I recommend eating leftovers taco casserole-style by setting a piece on top of a mound of crackers or chips and microwaving for about 1 minute. Recipe variation: Dip can also be made fresh and served like a casserole, but I prefer it as a dip.Recipe is naturally gluten-free and can be kept vegan by using vegan meat, sour cream, and cheese.
