This is a tweaked recipe from a family friend. It's awesome and makes a huge serving; perfect for potlucks. If not eating immediately, I put the cheese, onion and lettuce in a ziploc bag, the chopped tomatoes in a separate bag and keep the meat warm in a carrier [I like to keep it warm], then I assemble just before time to eat..mixing together and adding chips and dressing. I HATE soggy Dorito taco salad, so this fits the bill. My most requested "bring a dish" recipe!
