You bring up an important issue, Travis. We've found that we save a hell of a lot by meal-planning properly.
It's just us for now, so not terribly complicated, but what we do is plan a large meal that generates significant leftovers for lunches throughout the week that we make on the weekend, or at least prep to cook in the slow cooker early that week. We scale this up if we need to
feed more people, either making more, or making another large meal. We like to buy four cup pyrex containers with those gasketed glass lids to both take lunches to work, and to store leftovers in the freezer or fridge.
Personally, I favour things like curries or dahls featuring lentils, quinoa, butternut squash, tomato, and sweet potato, that I can eat either over rice or with naan, or both. I favour recipes that I can keep stocked in dry form in my pantry cupboard because you can buy the ingredients dry, in bulk, and keep them in air-tight glass containers. I also made a great accidental lamb korma with some frozen discounted lamb stewing chunks.
Fully half of our meal planning consists of keeping staples with long shelf lives and knowing how to use them in combo to make meals at need, and combining that with a solid leftovers usage strategy. Rehydrating dessicated and dried goods can require timing, but I think it's worth not losing good food to spoilage.
My parents, owing probably to cultural influences, tend to plan their meals around the meat being served, so the template in that case would be [meat]+[starch]+[large veg or two medium veg sides]=[dinner], say. That dinner formula could be adapted to some extent for non-meat diets, supplementing [protein] for [meat], and the composition switched around for different meals or requirements.
I have occasionally thought about having themed meal nights borrowing recipes from different cultures every week, seven or fourteen different ethnic food traditions on rotation, and several distinct recipes per ethnic tradition, but I think that might be a bit much for even me, and my better half and I
enjoy preparing food together in the kitchen.
Still, if variety of taste is an issue, I would resort to the "Italian night" or "Indian Night" or "Stirfry Night" options, maybe not even on fixed days of the week, but just as an organisational tool, where you could have a series of recipes organised by culinary tradition, all based on staples and spices in your pantry, handy, and probably there in the pantry or in a file on the door or whatever, so you can decide, on the fly, "Today is Indian night!," or "...Thai night!," and at once be organised
enough to have all the ingredients on hand and not be tied down to traditional boring weekly meal planning.
Great input already here, I look forward to others' meal planning life hacks.
