Sales on meats can definitely save you a lot of money, also buying your meat in bulk and then freezing it in individual portions can be very cost efficient. And also convenient when you are cooking for one person.
I prefer fresh vegetable just because I can snack on them whenever and they are also usually on sale at one of the many grocery stores. I am nowhere near a health food fanatic I just try to eat healthy most of the time, this seems to work great for me. I definitely feel like if I eat healthy all day, I will have a better workout.
