It's not super exciting but when I was lower carb, I'd cook up some ground turkey with seasoning and do a fried over easy egg... mix it all up, add some salt and good to go! Sometimes if I had higher fat I'd get some avocado in there also...
I don't know how low you want to keep the carbs but I do 2 whey protein coffee shakes. I find keeping the protein high is the key as that will keep the appetite in check and then just modulate the carbs around the workouts to avoid depletion.
