To assemble tacos: I like to toast taco shells prior to assembling, for an extra crunchy taco shell. To do this: Toast taco shells for 5 mins on 350°F in a toaster oven. Once shells have toasted, remove from toaster oven and start to assemble with filling. First place filling inside taco shells, then top with cheese. Place back into the toaster oven for 3-4 mins. Remove from toaster oven and top with shredded lettuce, tomatoes. Top with any sauce of choice: I like sour cream and salsa. Guacamole works great too!
