Amanda,
OAMC, or batch cooking (where you make many similar meals) is great at reducing your budget and reducing the cooking stress in your life!
Bulk or OAM cooking can save you a load of money. You tend to eat out less often because you can't think of anything to eat or you just don't have time. It's already done! Also, you can take advantage of sales and buy in bulk - then cook in bulk and have at least the beginning portion of a meal ready, if not the whole thing!
I learned to do 2 things to help with that "warmed over taste".
If a meal is highly intensive in preparing, but no biggie to cook it, I typically make up a bunch of the meals, then freeze uncooked. Then, I can just take them out the night before serving, let them thaw in the fridge overnight, and put in the oven at the usual time, but I don't have to do anything to it. A good example is lasagna. I just make sure that I only cook the noodles about 1/2 way before preparation, make them up (I happen to use a loaf pan to feed my husband and I with leftover for his lunch the next day). I line the pan in plastic wrap, assemble the lasagna, freeze it, then remove it from it's pan and store in a large freezer bag, removing all the air. Then, I just peel off the plastic, pop it back into a loaf pan and let it thaw. Then cook! I do make sure I have lots of sauce covering all the noodles so that they don't dry out in the process.
For meals that aren't intensive in preparation, I might cook 1/2 way or 3/4 of the way before freezing. That way, they still have cooking time left and don't taste "warmed over".
When boneless/skinless chicken breasts go on sale (at 1.99 or lower) I grab as much as my budget can handle that month (we usually spend $200/mo on 3 people and 3 cats). Then, I can do many things:
Cook up a bunch and cube to toss into salads, casseroles, etc. I keep at least 3 bags of just cubed chicken (2c in each bag) for impromptu meals or if I really want to cook that night.
I do some strips or cubes that are frozen along with ranch dressing that will later become nuggets.
I do quite a few different marinades that I can prepare in bulk, and store 4-5 breasts (to feed us for one meal and have at least one lunch leftover) in bags with the marinades covering them. This way, the entire time they are thawing, they are marinading.
When I can get ground beef on sale, I usually do a few things with it.
I boil it (yes boil...less messy than browning, gets rid of more fat and has a small texture compared to the larger chunks in browning - great for tacos). I then set some of that aside and make taco meat in a deep skillet, ,where I let it simmer for an hour or two, then bag in 2Cportions for a meal. I use some as filling in spaghetti sauce or other casseroles.
I usually make a batch of meat balls and meat muffins (cooked in muffin tins instead of whole loaves). They store easily and can be added to anything.
I hope this gives you some ideas to make some quick and easy meals for the freezer. Even if all you do is prepare some of the basics in bulk ahead of time, it'll save you an awful lot of time in front of the stove.
Here are some websites with great recipes and plans for you to check out. Please let me know if you have anymore questions.

Once A Month Cooking (OAMC) 
I am not crazy about the idea of standing in the kitchen for an entire day either.
