How about dal and rice? Lots of protein in that..
The basic recipe is 1 cup red split lentils, thoroughly washed, then cook in saucepan with 2.5 cups water and 1/2tsp turmeric (kurkuma). Cook for ca. 40 min, skim foam off the top as it boils, add extra water for your preferred consistency if you like it more soupy than porridge-like. While that's cooking, in a frying pan heat oil, add 1 large diced onion, 4 cloves garlic (minced), fry off until caramelised then add 1 tsp each of ginger, cumin, coriander, garam masala and chilli to taste (fresh or powdered). Heat until the spices give off a strong aroma.
When the lentils are cooked, beat with a spoon or whisk until creamy then add the onion/oil/spice mix to the lentils. Add 1 tsp salt, and stir through. Squeeze some lemon or lime juice over it before serving if you like. Done! Serve with basmati rice, naan or pitta bread and a green vegetable (like broccoli, or spinach)
Other variants: add coconut milk, mashed tomatoes, butternut squash, cauliflower, grated zucchini, spinach etc. etc. and try different split lentils/ split peas (most other kinds will need soaking first though).
You can use TVP or soy mince to replace minced meat dishes (like lasagne or shepherd's pie).. I don't personally bother I just make meals that don't imitate omni meals.
If you want to do something that is as much like "meat and two veg" as possible, make your spuds and veg as usual, buy a block of tofu, drain it, wrap it in kitchen paper, press out as much water as possible, dice it, marinate it in some soy sauce, then fry it in a frying pan with spring onions and mushrooms, or buy some big portobello mushrooms, roast those in the oven and serve with your spuds and veg with (vegetarian) onion gravy.
Or you could make this..
Moroccan Chickpea Stew:
In saucepan saute until softened 1 chopped (red) onion and 2 cloves
garlic, crushed. Add 1 tsp cinnamon, 1 tsp coriander, 1 tsp cumin, 1

(canned and rinsed, or cooked), 1 tin chopped tomatoes, 1 tsp veg.
stock, 1/2 cup raisins, juice of 1 lime (or lemon). Allow to cook for
at least 30 mins until flavours have combined. Just before serving add
4 cups spinach leaves, stir until wilted, serve with fried potatoes.
Any of that helping? I think there's a number of threads on here (see the top of the page) with good recipes and links to websites with many more..
try e.g. here?
Also,.. you probably need a lot less protein than you think anyway; one of my favourite, pre-vegan meals was still meat-free,.. it was just mashed potatoes with red cabbage cooked in red wine with sliced apples and a couple of cloves. Yum! ;-)
