I’m also diabetic and following a low carb/keto diet. These are some things I eat that are easy to throw together.
Chicken breast or browned ground beef with some Italian seasoning, low carb marinara (I use Rao’s), and mozzarella &/or parmesan cheese.
Hamburger Bowl- Browned ground beef with shredded cheddar cheese, chopped dill pickles, chopped onion, mustard, mayo, diet ketchup (I prefer G. Hughes). You could change the condiments to diet thousand island dressing (Walden Farms) and shredded lettuce to give it more of a Big Mac flavor.
Taco bowl- ground beef or shredded chicken with homemade taco seasoning (search keto taco seasoning for a recipe), cheese, salsa, guacamole, sour cream, chopped tomato, etc.
Tuna, egg, or chicken salad. I like to eat this on Quest chili lime protein chips, gives it a little kick.
Lunch meat and cheese sandwich with lettuce instead of bread.
Low carb “wings”- Shredded/chopped chicken with Buffalo wing sauce and ranch or blue cheese dressing.
For snacks or accompaniments I bring a cheese stick or a measured portion of nuts or berries. If you want something sweet try Lily’s chocolate, it’s sweetened with stevia and erythritol, I like the caramel sea salt the best.
