Inspire me and my picky family

[pushchair]

I am so sick of cooking and eating the same old stuff. Every two weeks I order from Sainsbury's, my favourites pop up with the old regulars and away we go again.
Trouble is that various members of the family will not eat:
Shepherds/cottage pie
Pie of any kind
Spicy
Anything in a sauce
Chips/mash/boiled potatoes
Veg
Lentils
Of course I do inflict things on them sometimes-veg, chips etc because I like them and they should like them!
To give you anidea of what I am sick of here is my menu from last two weeks or so excluding christmas:
Omlettes and chips, roast beef and trimmings, sausage mash and beans, southern fried chicken and corn on the cob, meatballs, potato wedges and brocolli, baked potatoes and tuna, chicken casserole and cous cous, pizza, macaroni cheese, spag bol, spag carbonara.
Help me with new cheap ideas please.

oh and I have browsed recipes but all seem too interesting for my idiots lovely family.

what about chicken kievs? can be served with cous cous, rice, salad, any variation on the humble potato.
Also you could try making a risotto.
Soup is warming, can be made very cheaply and is a sneaky way of getting more veg into their diets without them knowing. Just blend it all together, they will never know.
French onion soup is also very easy - chop a large onion, fry in butter until softened then add a couple pints of stock and boil for about 15-20 mins. serve with lots of crusty bread.

Also notice you make no mention of fish, I bet there are loads of nice things you could try cooking with seafood.

Home-made pizza with sneaky veg in the tomato sauce? I'll put a recipe on if you think that's the kind of thing.

Try Noodles, Blue Dragon instant type or similar are fine, these can be done with Sausages for a really quick and filling lunch
Or try onions, pepers, garlic & chicken fried in a little oil, add gravy granuels to about 150ml of water and add to the already cooked noodles, stir, add the cooked noodles to the meat and veg and stir well, this makes a kind of gravy NOT sauce, I like to add chilli bits/flakes also to the noodles when cooking but these can be added at the end after you have taken out the portions for those that dont like spicy.

Pasta with above chicken and veggies and tomato paste and water with variety of mixed spices (they dont have to be spicy, can be just tasty)

My Son wouldnt eat shepherds pie either until we changed it a little and added tomatoe paste and called it Grandmas Dan Pie - Daniel is his name, funny how such a small thing made the difference
