What was a normal day food wise for her before?
We limit pasta/rice/wraps etc to only a couple of dinners a week. We eat a lot of sweet potato though.
Staples for us are:
Piles of any roasted veg (we usually do broccoli, red pepper, courgette, onion, parsnip) with some roasted sweet potato too, sprinkled with feta cheese (could add sausages or some chicken, but we don't eat meat)
Stew made with onions, tinned chick peas, tomatoes and white fish. Throw in fresh chopped parsley at the end
Lentil dal with hard boiled eggs
Fritatta, can put any veg or meat in, salmon and broccoli is nice
Warm salad with puy lentils - again nice with little chunks of sweet potato.
Red onions cooked slowly with balsamic vinegar then add fresh spinach and tinned green lentils (drained and rinsed), serve with sausages (we have quorn). This is yum and much simpler than it looks
Sometimes I make a 'loaf' using red lentils (lots of recipes online) and serve with cauliflower and broccoli cheese.
Could also try skewing ratios so make say a curry with a pulse such as lentils or chick peas, so it's filling, and serve with a small portion of brown rice. Then most of the meal is less carby. Same with pasta make tomato based tuna pasta sauce but add sweetcorn and broccoli, make the sauce chunky and satisfying then have a small amount of pasta with it
