Preheat oven to 350˚F. 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/taco mixture. 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.
Take from oven and remove foil from crackers. Cover with fresh chopped tomatoes and sliced green onions.
