Hi OP
My DP doesn't eat meat so we tend to eat veggie at home. We eat a lot of curries at home in various guises, mainly because we both love flavor and spice, and one pot cooking is my preferred cooking style.
+1 for HFW veg everyday book btw, great recipes and also a nice read.
I am going to give you some of my reasonably easy, highly tasty favorite veggie recipes.
On the really easy scale, any veg plus a tin of green lentils, plus a tin of chickpeas plus a jar of indian curry sauce is really nice.
Butternut squash thai curry.

Add a red pepper too, and I use a whole tin of coconut milk and no stock.
Chard, sweet potato & peanut stew

Quite interesting, go heavy on the spices though (I prob double them)
Quinoa meat balls

Use a tin of lentils for speed. Don't fry them, they spit horribly, they come out very nice baked in the oven at 220 dec for 25 mins (ish) esp if you spray with an olive oil spray and turn and spray half way through cooking. Serve with pasta and a rich tomato sauce (2 x cartons pasata, 2 x tablespoons balsamic vin, salt, pepper, tablespoon oregano, handful of basil leaves and reduce down by 1/3)
On reflection this isn't really a weeknight meal but IT IS SO YUMMY
Yotam Ottolenghi's Multi vegetable paella

Do all your chopping first because it gets busy once you start doing things.
Beetroot risotto with griddled veg.
This looks AMAZING.
Follow a basic risotto recipe but after you have fried off your risotto add a bunch of grated fresh raw beetroots. Fry for a bit, then add rice and continue on. Grill or do in a griddle pan some asparagus, baby courgette, something like that to serve with. Oh oh oh chopped walnuts is a must to scatter on top.
If you can stand the prep, Yottam's aubergine and lemon risotto is one of the nicest things I've made recently. This is not a weekday thing.

Veggie chili just sub in quorn mince. Top tip a couple of jarred roast red peppers add some extra smokey flavour.
Veggie fajitas (peppers, onions, courgettes and maybe broccoli - just omit the chicken) with refried beans, or these ones here are lushtastic :

In fact, anything from her blog is lush but a lot of it takes quite a bit of prep. The veggie kofta korma is quite simply the most divine thing ever.
I like tagines to, try these two:
