In a large shallow dish, like a pie plate, whisk together the milk, egg, vanilla, cinnamon, and sugar.
Dip the taco size flour tortillas in, one at a time, saturating both sides with French toast batter.
Place the coated tortillas in a hot buttered skillet. Cook on each side for a couple minutes, until the French toast tortillas have lightly browned.
Remove from the pan and set aside. I like to put mine on a wire rack lined baking sheet and I keep it in the oven at 200 degrees to keep them warm while I'm preparing the remaining tortillas and cooking my scrambled eggs.
Fill your the French toast tortillas with warm scrambled eggs and bacon/sausage. Drizzle with syrup and top with chopped green onions. Serve immediately.
**Increase your French toast batter as needed if you're serving a crowd. The batter recipe provided will make about 8 tacos.
