Need Help for planning "Frugal" weekly menus

[*LizziesLoops*]

Hey mamas! I'm trying to cut down out grocery bill and start actually planning a weekly menu with recipes that are "frugal" I'd like to keep meals to under $10 each daily meal so I can manage to spend about $70-80 a week on groceries. I'm a decent cook and can manage to follow most recipes but really have no idea how to plan and shop for a weekly menu. I'd really like to use recipes with a minimal of prep. time and also avoid a bunch of pre-packaged foods. We generally do a frozen pizza every Tuesday (dance classes so not much time for dinner)...so that's easy at least...but I really need help making meal planning easy and inexpensive. What do y'all do for meal planning?
