My DH was the same, until about a year ago when I started ignoring the complaints and he realised what a super easy/cheap meal it is, and really quite yummy! We have jacket potatoes stuffed with: cheese and beans and coleslaw on the side cheese and beans and veggie sausage on the side! not too imaginative but lovely though, the veggie sausages are great too and they are usually under 100 cals each if any one is dieting!
Just remembered...my MIL always used to have a jacket potato dinner on a Monday night for her family. So it was always the off cuts from the Sunday roast and any other bits and pieces left-over, with just a salad.
Rather partial to half a pound of butter myself....
But also like:
Ratatouille Chilli either con carne or sin carne Sour cream, grated cheddar and chives Grated cheddar and onion gravy (don't knock it - it's yum!) Crispy bacon, mushrooms, onions and pecorino Tuna and sweetcorn mayo Beef stroganoff - you need only really make a portion for one to serve two with a large jacket spud and salad, so still economical. And use minute steak - nice cheap cut, but feels like you're having something more expensive and substantial
We often have JP for dinner, even meat and two veg DH does.
