This classic comfort food will be a family dinner hit.
Preheat oven to 350°F. In a large skillet on medium-high, add sausage and cook until browned while breaking it up with a wooden spoon for about 5 minutes. Add onion and bell pepper and continue cooking while stirring occasionally, until tender, 8 to 10 minutes.
Whisk together eggs, milk, hot sauce, salt, and black pepper in a big bowl. Arrange tots in an even layer in a lightly greased 3-quart baking dish. Top with 1 cup cheese and the sausage mixture from step one. Pour the egg mixture you just made evenly over tots and top with remaining 1 cup cheese.
Bake until set in the middle, 50 to 55 minutes. Let it sit for 10 minutes, then top with jalapeño and chives and serve.
