My cheat meal still requires some fore thought but it is so easy. I cut up a few cloves of garlic and stuff it inside a whole chicken, sprinkle a little oil on top with a dash of rosemary and salt: roast at 400 for 1.5-2hours. The actual prep time takes 5minutes. I serve with roasted asparagus (easy to lay them out on a cookie sheet and drizzle oil on and roast for a few minutes).
another cheat meal is cooked ground beef, frozen cubed sweet potatoes, a chopped onion, a few chopped white potatoes stir fried until the potatoes are soft to poke with a fork, and then I mix in some spicy tomatoes sauce and some chilli powder and salt. I call it sweet chilli hash.
