Thaw the phyllo dough according to the package.Spread out the Phyllo according to the package. Keep the sheets moist by covering with a damp cloth or paper towel. It can be a challenge to work with so take your time.Cut 4-6 phyllo dough sheets into 2 x 2-inch squares. Fit them into lightly oiled mini muffin pans. Pop them into a preheated oven and bake for a couple minutes or until lightly browned.
Fill each mini phyllo cup with taco meat, chopped lettuce, finely shredded cheddar cheese, sour cream, taco sauce, and green onions.
Keeping the phyllo sheets moist, but not too moist is the key to successful handling. Too moist and it gets gummy, too dry and it cracks.
