If I had those restrictions I think this weeks meal plan would be -
Sun- nut roast with roasted parsnips, carrots, Yorkshires, veg gravy, and mash- either buttery leek mash or swede and potato mash- make extra for leftovers
M- Fish cakes( made with leftover mash and a fillet or two of salmon) and salad ( just mashed potato cakes and salad for dh)
T- butternut squash and roasted red pepper lasagne
W- fish tagine / chickpea for dh tagine with cous cous or flatbreads
T- mezze- Spanish tortilla, garlic and chilli prawns, red pepper humous and crudities, roasted pepperdew peppers stuffed with feta, etc
F- pea and mint risotto / pea and asparagus risotto/ squash risotto / leek risotto - dependant on season/ what's cheap in whoppsy aisle - make enough for leftovers
S- arancini with leftover risotto and mozzarella - maybe without mozzarella for dh. But he'd be missing out
But I'm not sure if I've enough protein for you and perhaps I'm also heavy on the cheese- I'm not very good at this am I
