I recently made a "Big Mac Flatbread" using ingredients for Aldi and they turned out great! The whole family loved them, especially because they were customizable. 

Ingredients: 

1 lb ground beef

1 T worcestershire sauce

1 tsp onion powder

2 cups shredded cheese

toppings: shredded lettuce, diced pickles, red onion, fried onions, etc

For Big Mac sauce: 

1/2 cup mayo

2 T sweet pickle relish

1 T yellow mustard

1 tsp white vinegar

1/2 tsp onion powder

1/2 tsp garlic powder

1/4 tsp paprika

To make: 

1. Preheat oven to 400 degrees
2. Cook ground beef and drain. Add in Worcestershire sauce, garlic powder, onion powder
3. Mix together Big Mac sauce
4. Lay out flat breads (we used a pack a half large ones from Aldi-- 3 flat breads)
5. Spread out sauces over flatbreads. Sprinkle on cooked ground beef and shredded cheese
6. Cook in over for 5-10 minutes, or until cheese in melted and flatbreads are as crispy as you'd like 
7. Remove and top with desired ingredients
8. Enjoy!
