Lentils lentils lentils!! They are high in protein and fibre, taste lovely, are cheap, and apparently lower your risk of coronary heart disease! I use them in at least 3 or four meals a week, from soup and curry to vegetarian 'meat'loaf and 'meat'balls.
Also, beans beans beans! We buy tins of kidney beans in bulk, and throw them into everything they will go with - even things they don't!
Also, we eat tofu at least twice a week (Cauldron Brand from Sainsbury's, 3 for the price of 4 right now - buy loads and freeze). As Andee mentioned, it's great in stirfrys, also great in currys, soups, or just marinated and grilled.
And my favorite meaty substitute is dried soya mince. We use Sainsbury's own brand, and it's unbelievable cheap, very high in protein, and has nothing funny added. It can go into anything that calls for beef mince. My favorites are chili, tacos, spag bol, lasagna, etc.
We used to use Quorn alot, but I've been reading about some disturbing reactions some people experience from Quorn products. The fact that it's made from processed fungus always kind of gave me the heebeegeebees anyways, so cutting it out of our diet wasn't too hard. I'm not a mushroom eater, so perhaps I'm just suspicious of fungus!
We try to avoid the veggie sausages and burgers because there's so much stuff added to them, but we'll occasionally splurge if we fancy bangers and mash. Sweetcorn fritters are a cinch to make up when we fancy veggie burgers, although not all that high in protein.
Congrats on your making your first moves towards the green side!
