I haven't thought too much about this so don't judge the nutrition but just always think to make every meal take at least one step out of the following days lunch and dinner. Probably a bit cheese heavy but as an idea...
Sunday dinner roast a massive joint with double amount of roasted veg
Monday lunchleft over roast dinner.
Monday dinner curry made with left over roast meat veg and serve with rice.
Tuesday lunch left over curry with jacket potatoes. Cook extra jacket potatoes.
Tuesday dinner penne with bolognese, cook double sauce and and pasta. When serving put half the pasta to one side and add pesto.
Wednesday lunch reheated jacket potatoes with cheese and spring onion or beans and cheese etc
Wednesday night lasagne from left over bolognese, just make a cheese sauce
Thursday lunch, have the pesto pasta with cherry tomatoes, chopped peppers etc
Thursday dinner make a lamb or sweet potato and chickpea tagine. Have with rice.
Friday lunch left over tagine with cous cous, only have to add hot water.
Friday night stir fry with egg fried (leftover rice)
Saturday lunch Gammon joint (I like nigella's ham in cola in the slow cooker) with veg and however you would like your potatoes.
Saturday Night macaroni cheese with left over gammon.
Sunday lunch left over Mac and cheese or ham and mustard sandwiches (one sandwich won't hurt!)
