OP I've been exactly where you are (and still am) - I like a proper meal, not just 'roast cauli and chickpeas' even though I love those two things. I ask this question and get 'well you can make shepherd's pie with lentils' or 'try this vegan website' when what I want is someone's personal favourite veggie meal that they look forward to and would cook for someone else!
I want to get more into beans and pulses.
There's a bean stew with halloumi recipe on BBC good food, which I like as it's an excuse to eat garlic bread with it.
There's a good aubergine, mozzarella and orzo bake recipe here but it's not the quickest thing to throw together at all https://smittenkitchen.com/2012/09/baked-orzo-with-eggplant-and-mozzarella/
Roasting Tin has a few nice ones, like roasted chickpeas, corn on cob and onions with a yoghurty sauce.
I'll try more mexican bean things I think, as I love savoury spices + cheese + sour cream.
Chickpeas are fab in curries but I do tend to think meat in curries is amazing so I can't say it'd convert anyone.
I have a great satay chickpea recipe but on closer reading it looks like it was largely copied off that Ottolenghi one above, crispy onions and all!
This is nice although I get bored eating soup halfway through - this is one of the few I like https://www.bbcgoodfood.com/recipes/curried-lentil-parsnip-apple-soup
Quarter aubergines lengthways, coat in a mixture of miso, soy, honey and oil, and bake for an hour turning every 15 mins (in a roasting tin on parchment). Have that with rice, spring onions, plain yoghurt, bit of chilli and coriander leaves. It's probably similar to the nasu dengaku pp mentioned. The yogurt mixes with everything and sort of makes a creamy fresh sauce. They shrink and shrivel but go really tasty!
