In a large skillet over medium-high heat, crumble the chorizo sausage into the skillet and cook and stir until fully cooked. Remove from heat. Heat another large skillet to medium heat.
Lightly spray the skillet with cooking spray. In a medium bowl whisk together eggs, milk, salt, and pepper. Pour the eggs into the skillet. Cook and stir until almost firm. Add the sausage and continue cooking and stirring until firm. Remove from heat.
Heat tortillas according to package directions. (Stovetop or in the microwave).
To make tacos- sprinkle shredded cheese on each tortilla. Top with the scrambled egg and sausage mixture, add hot pepper sauce (if using), and top with salsa.
