I'm going to keep a running list here. Add yours in the comments!
1. Tuna salad with cucumber slices as "scoops".
2. Taco-less Taco salad - lettuce with taco seasoned beef, chopped tomatoes, sour cream (or sub shredded cheese).
3. Bunless hamburger - Hamburger (or bison or turkey or chicken etc.) patty plus all the non-carb fixins' (tomato, cheese, mayo, avocado, pickles, onion, etc.)
4. Guacamole or hummus with cut up peppers, cucumber, or carrots to dip.
5. Raw pumpkin or sunflower seeds. Delicious and snackerish.
