Make your secret sauce! Mix together all ingredients mentioned on the secret sauce list. This makes a TON of sauce, so you’ll be able to use it for a few weeks (keep it till the yogurt expires)
Next, make the buns! Mix Greek yogurt with flour. Combine and cut into 4 equal parts if you can. Take each part and separate into 3 parts (2 smaller and 1 a bit bigger). Form your bottom, middle and top buns. Egg wash and sprinkle sesame seeds. Bake at 375 for 20 minutes and then broil for a few till golden.
Cook the burgers. Divide burger meat into 8 thin patties. Cook on skillet until done. Set aside.
Finally assemble! On your bottom bun, add half a tablespoon of secret sauce, a few diced white onions, diced lettuce, pickles and a slice of low fat cheddar cheese. Top with a burger and then add middle bun. Repeat the same steps but don’t add another piece of cheese. Top with the sesame seed topper!
