Right now we have no kitchen - luckily we do still have the oven (but have mostly used a remoska in the front room) our hob is working but I feel your pain
In a casserole dish rice with veg chopped into it (mostly root veg) pour on stock till it's covered add herbs you like, rub chicken portions in olive oil plonk on top GM 5 till chicken cooked.
Bunch of root veg olive oil, leeks and mushrooms to add a little later - either oven cook some sausages or some more chicken to put with it.
Second the baked spuds with cheese, tuna, coleslaw ect ect.
Same with the salmon parcels (try lime and corriander leaves) - done with yet more roast veg alongside.
Casserole/Hot Pot - either with meat or lentils, or both.
Mix up eggs, milk some SR flour (till it looks a bit like omlette/thin batter), different veg - pepper, courgette, mushrooms, peas, sweetcorn ect put in a greased tin and bake at GM 4 till middle is solid - pastryless quiche type thing, with salad and maybe more baked spuds.
Cheese tart - puff pastry, tom puree (sundried makes it very yum) then add stuff you'd put on a pizza and bake - another one for salad. Or make a pizza with a shop bought base.
If you buy the white sauce (or can stomach the powder packet stuff) you can make cauliflower cheese or macaroni cheese, more baked spud and roast veg.
You can make veg chilli in the oven with a casserole dish, just add everything and cook till the pulses are done - have it with something like cous cous that can be made with the kettle instead or rice. I've never coked with red meat so I don't know if it can be done this way with mince and I don't like soya mince so all my chilli's are just veg, pulses, kidney beans and a ton of mushrooms for texture. (well we like it!)
One thing that has really helped - and wasn't just a stupid expense has been a potatoe chipper from lakeland - but we have used it for everyroot veg you can think of inc beetroot. With all prep on a board in the front room it's been well worth the stupid price we paid for it.
