@WheresTheEscapeKey - re: meal plans... not the same as @bluesky45's meal plans obviously, but I use a meal plan I saw on a thread a few years ago that I find helpful (I can't find the post now but I kept a copy of the meal plan).
It's weekly meal plan with the same basic ingredients each day of the week so it makes shopping easy, but still allows a bit of flexibilty.
Sun - Roast chicken/meat, or casserole, veg, mash or new or roast potatoes,
Mon - Fish (could be fish pie, battered fish, fish fingers or fishcakes, tuna and pasta bake).
Tues - leftovers from Sun - meat or chicken cuts mixed with rice, pasta or noodles and sauce, or made into a thick soup with croutons, bread rolls or garlic bread or baguette. If no left-overs then macaroni cheese or pasta of some type drizzled with olive oil and mixed with sundried tomatoes and topped with grated cheese.
Wed - Mash or jackets - could be jacket potato and filling; or bangers and mash, shepherd's pie, or bubble & squeak. Veg or salad
Thurs - Egg based meal - egg & chips; quiche; egg bacon and beans; ham & eggs; french toast. All with salad.
Fri - As Monday
Sat - Pizza or a ready meal, or home made burgers/hotdogs, or english cooked breakfast for dinner, or any shop offers. Salad.
