3. Cabbage
While lettuce is great for cold salads and sandwich wraps, cabbage can do the job nicely for warmer meals. You can again use this to replace the carbs that often go on the side of your plate by just adding a little cabbage or red cabbage.
Better yet, why not learn some Polish recipes like golumpki or bigos. The first is beef that has been wrapped in cabbage and dipped in a tomato source. The latter is a mixture of various meats with cabbage and sauerkraut. Both are delicious and carb free!
