Re:
As others have said, there are lots of good veggie recipes online.
If you like Italian food, try Gino D'Acampo's Veg Italia for lots of good dishes. Or vegetarian pasta bake is dead simple: I do it with aubergine, butternut squash, mozzarella, a tomato sauce with onions, garlic, Aleppo pepper and ample 'Italian herbs', 50:50 pasta and a cheddar topping. Just pre-cook everything, frying the squash first, because it takes longest; shove the lot in a baking dish, grate cheddar on top, and bake for 20-25 minutes until it starts to brown on top. Alter the veg to suit your taste.
A good, quick, light meal is halloumi kebabs. Chop up lettuce (iceberg works best), tomatoes, cucumber, spring onions. You could add spinach, watercress, etc. if you wanted. Slice halloumi and fry without oil until it starts to brown (you don't need oil: it releases a lot of moisture as it heats). At the same time, heat pitta bread under the grill till it's warm and perhaps beginning to puff up, but not till it starts to go hard. When the pitta and halloumi are done, slice one side of the pitta, liberally spread houmus inside, put in a layer of sliced halloumi, stuff as much salad in as you can and eat. It's more of a summer dish than a winter dish though.
