The daunting part for some is the thought that they'll need to prepare & cook 7-21 meals a week. I cook eggs & burgers in real time, but mostly cook roasts & stews in big batches a few times a month and freeze the intentional leftovers in single servings to reheat & eat. The pre-cooked meat/poultry/fish can be added to a salad or steamed with some flash-frozen low-carb vegetables and voila, dinner in ~3 minutes. Virtually all of my protein sources are bought when they are on sale. I have a Starfrit burger-shaper that I use to shape ground beef, chicken or turkey (on sale!) that I season myself and make into patties (each w/30g of protein), and freeze raw. 8 minutes from frozen to done in my George Forman grill. Yes, my freezer is full and my fridge half empty, but I never have an excuse that there are no real, on-plan foods ready to eat.
