Yesterday did a curry in the slow cooker with Quorn pieces, mushrooms, peppers, courgettes, green beans, carrots, sweet potato and sweet corn. Would serve that with rice and garlic bread, also you can get ready made frozen chappatis that you just flash in a non stick frying pan, get mine from Asda. They are wholemeal and very filling.
Today there is a bolognaise sauce in there, using Quorn mince and then all the other stuff you'd use for a bolognaise mushrooms peppers, tinned toms, a whole bottle of red (it's a big slow cooker!) garlic, tom puree black olive puree, mixed herbs etc. I've mixed half with cooked penne pasta and put cheese sauce on the top to make an easy 'lasagne' and will freeze this. Serve with salad and a jacket spud or garlic bread if you're hungry. I make this loads and lots of my dh's mates are bikers with a big meat appetite and yet they all say that they didn't even realised there was no meat in it.
The other half is still in there and I have added cummin, coriander and lots of chilli powder, will freeze up as chilli.
We eat a lot of pasta, I make pastry in large amounts and then freeze to make an easy quiche. A big chunk of that with a jacket pot and a big salad, mmmm. Also, frozen puff pastry veggies sauteed and mixed with cheese and pesto or similar, then made into lattice, again, could serve with jacket spud or roasties and veggies like a 'proper' dinner! 
Don't use loads of lentils, but do a fab and really easy curry ; just coulple big spoons of madras paste, Quorn chunks, sweet potato, red lentils and veg stock, and whole tin of coconut milk. Let it simmer til lentils cooked and thickened then chuck in loads of spinach. It is really quick, simple and filling.
Hope that helps.
