I try to revamp the general food menus 3-4 times a year. So our summer menu looks different than our fall menu for example. I have a Summer, Fall, and Winter plan on the computer. I don't seem to have a Spring one... I guess I jumped Winter to Summer last year? I don't record the recipes, just the names/ideas. Then I have recipes saved separately on the computer, or I record what cookbook and page a certain recipe is in.
I don't plan out all the meals for all the months at once, but I spend a full day thinking about ingredients that are great for that season/in season fruits and veggies. I pull up a list of the menu idea lists I generated for last summer, fall, etc. I flip through magazines I have and recipes I've gotten from mags and friends and family. So I have a "Winter Meal Ideas" list which is different from my meal plan. If I feel OCD about it, I categorize them by stuff like "pasta", "soups" etc. Summer meals are less cooking, lighter, faster, because we're often busy. Winter meals are stove/oven heavy to keep the place warm.
When I do the meal plan for the month, I pull up that season's list and look for things that it makes sense to make together (like, I'm buying pumpkin, and there will be lots, so let's do pumpkin lasagna and pumpkin dip) or not (like, DH is not going to be happy to eat 3 bean meals in a row). Some stuff never makes it off the idea list bc it seems too time consuming or I can't adapt it to something DD will eat, etc. But some are priorities, like I've been wanting philly cheese steak even though I haven't had once since I originally went veggie a decade ago. So I put veggie chicken philly cheese steaks on the winter menu.
: We've had them twice now-Jan and Feb. They're on the menu for March too!
This way I use seasonal stuff, but we don't get too sick of stuff either. So when summer rolls around, gazpacho soup will still sound good to me, because we haven't had it since last summer. And we have some year-round staples too. They always go on the idea list (spaghetti and tomato sauce, black bean wraps, veggie chili, veggie burgers, falafel, quesadillas, mac and cheese) and they make it on the meal plan if they sound good and not "not THAT again!" DD is telling me now that she's "mac and cheesed out."
