Preheat oven to 400F. Lay out each slice of bacon on a baking sheet, lined with parchment paper.
Place the sheet covered with bacon into the oven, bake until golden and crispy. Lay out the cooked bacon on a paper towel to get rid of any extra grease.
Whisk milk together with eggs and season with salt. Heat the pan up with oil, on a medium high heat, and pour in egg mixture.
While the eggs are cooking, keep on stirring and breaking eggs into small pieces. Remove from heat once they're cooked.
Slice mushrooms. In a hot skillet, fry them with a bit of oil until they turn golden brown. Season with a bit of salt.
Build burritos by placing a little bit of each ingredient in the middle.
Fold the sides of the tortilla inwards and roll the burrito tightly together.
