In reference to the question of getting organized, I have the following system...
I know what my family likes and doesn't. I guess you will need to make a few new menu items each week and jot down the good ones...
I keep two calendar's with room to write notes for each day. First we fill the activities calendar. This is when soccer games are, dr's appts., etc. I am strict with this. If the kids neglect to tell me something and I have to change dining plans, there are consequences...
The second calendar I write out a meal plan weekly. This way I can look back at the week before and try not to duplicate too many meals. The weekly meal plan is done PRIOR to the weekly shopping (Well actually I am a monthly shopper, but most people prefer weekly). Left overs are only once every two weeks, but on the oppposite week, some meals are twofers (two meals, one preperation). Make sure to look back at monthly meals for idea's the next month. Also, peoples tastes change. Make sure to note any changes. Leftovers are great for lunches..
I put ONE, yes only ONE, yellow star on the calendar. This is for one day during the month that I can just throw in the towel and we eat out. Usually a pizza, but sometimes it is something else....
Go to the library and get simple cookbooks. If you are just starting out you are better off with Betty Crocker than Mario Batali. Keep rotating the cookbooks and write out recipe cards. Put them in a cheap photo album or 3 ring binder by category. Cookbooks made from school's and or church's seem to have good old-fashioned meals and recipes. Don't be afraid to substitute to your liking... This is from one of my other threads but thought it might help a bit, Diane.
I can purchase 1# of 90% lean ground beef for $1.99 or $.50 per person for a meal. Here are some of my favorites that enhance my budget.
