Great stuff. I always prep my dinner in the morning while sipping my coffee and come home to delicious, ready made meals. Here's a past thread where we kicked around some recipes:
Another I've been specializing in lately is simply (animal flesh, preferably something fatty like a roast, or a whole chicken/drumsticks/wings, or lamb shoulder, or pork shoulder) + 1 pound carrots + 1 onion + 1 potato.
Good idea. I know budgets can be tough, but if you have the means, grass fed beef is well worth it IMO. You can also do tricks like buying bone-in and cheap cuts of meat (I buy bulk orders of wings, drumsticks, livers, etc).
Everywhere. Anywhere. Just so you're eating something with nutrients besides meat. I don't know how religiously you need to avoid "carbs" during the day but I can't imagine the carb hit from a handful of kale is such that you can't have some with your lunch.
Outside my expertise, I'll refrain from comment.
