My first suggestion is to get different cookbooks - or look on-line. I use
Cooks.com - Recipe Search and More - they have really good, really simple recipes. I also get the Kraft magazine which has recipes featuring Kraft food items, but I just substitute generic brands usually since that's what I buy.
I also get a lot of magazines and cut out recipes from there. I use magnetic photo albums to store my recipes in. I make a table of contents for each so I can find them faster.
If I cook a meal that can be frozen for later, I'll double the recipe. For instance, meatloaf. We'll make one to eat and one to freeze. Same with casseroles and soups. For soups, I freeze them in small portions so that we don't get sick of it before it's gone. By small, I mean 1-2 serving sizes. I'll have it for lunch or a snack.
Since I stock up on meat when it's on sale, I usually have it stored in my freezer. I'll see what's in there and then make a meal plan using that meat. The day before I go grocery shoppping for the week (usually on Sun), I'll put together a meal plan for the week, listing each meal I'm going to make. To decide what to make, I look through my cook books, using what meat I have in the freezer or what is on sale.
If I don't do this - we end up eating out a lot (like every other night) or having pasta several times a week.
Speaking of pasta, I had the best idea last week. I grilled marinated chicken and veggies on the grill for dinner one night and then the next night, I made vegetable pasta using the leftover veggies. I sauteed garlic in olive oil, then added the veggies and cooked for about 7-8 mins. Then I added cooked pasta and mixed it all together. Took it off the heat, added freshly ground parmesan cheese and it was delicious!
Hope this huge email helps!
