In a large skillet, brown the ground beef and season with taco mix. Set aside.
Spray a 24 oz. Au Gratin dish or 9” deep dish pie pan with non-stick baking spray.
Evenly spread 1 can of fat-free refried beans on the bottom of the dish. Top with ground beef, then sprinkle with Mexican blend cheese.
Layer the Crunchmaster™ Signature Buttermilk Ranch & Dill Multi-Seed Crackers around the outside of the dish in an overlapping pattern. Cover crackers with aluminum foil to prevent over-browning.
Bake at 350˚F for 15 minutes, until cheese melts and dish is warmed through.
Remove from oven and remove foil from crackers.
Cover with fresh chopped tomatoes, avocado, sliced green onions and sour cream.
