You can eat beans as the protein part of SP. So you could make a vege chilli using quorn mince peppers, kidney beans, tomatoes and have with a big plate of veg eg green beans, broccoli.
Mixed bean casserole (any tinned beans any veg eg mushrooms, peppers, aubergines, stock cube, passage, whatever flavouring you like) then instead of potato you could roast butter nut squash chunks with fry light, or mash swede or celeriac.
The potato substitutes are also nice with low fat quorn or other free sausages eg the LM rosemary and onion ones.
Quorn cottage pie? (Quorn, onion, chopped carrots, chopped celery, passage, stock cube topped with mashed swede) or you could do similar with beans - replace the quorn mince with drained mixed beans, top with slices of swede like a hotpot. Serve with green beans or roast butter nut squash.
Slimming world hummus (mash tinned chicken peas with garlic lemon juice, water to get the right consistency, salt and pepper) with crudités as a snack.
Bean salad using fat free salad dressing and lots of chopped salad veg mixed in (tomato, peppers, steamed and cooled chopped green beans) is a good lunch or you could make soup (loads of free vege, onion, carrot, celery, passata, stock Cube, water depending on how much you are making, then add Half a can of beans, blend then add the rest for texture)
