Preheat oven to 350 degrees.
Arrange pita chips on a baking sheet and sprinkle with shredded cheese. Place in oven for 3-4 minutes until cheese melts.
Meanwhile, in a medium bowl, whisk together eggs, milk, salt, and pepper.
Add oil to a large skillet over medium-low heat and, pour egg mixture in. Let eggs sit for a couple minutes until they start to set and firm up at edges. Using a spatula, begin to pull the eggs in from the edges to the middle of the pan. Continue this motion until eggs are cooked completely.
Scoop scrambled eggs over pita chips. Sprinkle on crumbled bacon and add avocado, sliced tomatoes, sour cream, and scallions. Drizzle with hot sauce, if desired.
