For convenience foods, Sainsburys do the yummiest spicy bean burgers (in the frozen section).
This Nigel Slater curry is delicious
I really like Felicity Cloake's dal recipe (in fact am making it now!)
In summer, grilled halloumi with salad is yummy - google Ottolenghi, he has lots of great halloumi recipes (or spring for one of his books, they are amazing!)
I also make a big greek salad (chopped tomatoes, black olives, cucumber, red onion, feta cheese, olive oil, a nice vinegar of some description) and mix with quinoa for more protein.
Oh, home made hummus? blitz chickpeas, tahini, olive oil, garlic and lemon to taste. Add coriander, chillis, other herbs that you like to mix it up.
