I've low carbed for years. It's a lot better now than it used to be because there are low carb breads and pastas and tortillas that you can use. That's helped tremendously! I'll give you some ideas, and you tell me which ones you want more info on, k.
If you can find Dreamfields low carb pasta, you can do lots of stuff with that. Get the elbow macaroni, and you can make mac & cheese. Low carb penne pasta, and you can make chicken alfredo on penne pasta. They make low carb spagetti, but you have to go very easy on the tomato based sauces because they're carby.
With the low carb tortillas, you can make wrap sandwiches. I like ham and turkey with cheese and dip in ranch dressing. You can also do chicken or beef enchilladas. yummmm.
Low carb bread makes good sammiches, and grilled cheeses are totally legal with it.
I have a good way to do oven fried chicken. I also roast chickens.
You can do a beef roast using Lipton's onion soup mix.
Anything you want more info on, just holler.
