I either go to Burger king and get a tripple whopper with no mayo or ketchup, sub with LOTS of mustard and pickles, then i remove one bun.
Or I go to Carl Jr's and get the superstar same as above but just ask them to make it low carb (wrapped in lettuce).
Third option is I go to KFC and just buy a few breasts, remove most of the skin.. peel and eat.
Fourth option is I get roasted lamb from guys who sell it on street corners where I live. Its really delicious but the meat is super fatty. Low carb for sure tho.
Fifth option is I just walk into a hole in the wall resto and get them to "make it my way". Mix and match stuff from the menu. Like an order of sweet and sour cabbage, but with three of the "extra chicken" option from the noodle dish added. Lol gets some funny looks, but it works.
