I am similar to you - not veggie or vegan but like to eat veggie a lot of the time!
The Food Medic has lots of yummy veggie and vegan recipes on her Instagram and website

they are all easy to make with not too many special ingredients!
For lunches - I add feta/mozzarella/hummus/guac to most of these:
Soup and a nice roll
Falafel in a salad/pitta/wrap
Cous cous / quinoa with sweet potato, chickpeas, veggies etc
Frittata with various veggies
Pasta salad with veggies, feta/mozzarella
Spicey rice salad with sweetcorn and avocado
Beans on toast
For tea:
Pasta in pesto/sauce and veggies
Pasta in tomato sauce with fake meatballs or fake sausages
Veggie stir fry with some toasted cashews on top
Egg fried rice with oowds
Fajita veggies and chickpeas with rice
Bean chilli
Veggie curry
Veggie/bean stew on baked potato
Veggie / fake meat wraps
I also prefer oat to almond milk. And Alpro chocolate milk is sooo good! Alpro also do good yoghurts and pudding pots.
Ben and Jerry’s vegan ice cream is
You will be surprised at how many of your usual snacks are “accidentally vegan”. Oreos are vegan and most crisps are!
If you’re out and about, most supermarkets and coffee shops etc have veggie/vegan lunches and cakes. Most restaurants have good veggie/vegan offerings too
You can get loads of good meat substitutes tbh, it’s just trial and error to find your faves I think. The Linda McCartney sausages and burgers are really good and I always have a pack in the freezer!
If you are a wine drinker watch out because not all wine is vegan!
That’s all I can think of for now but I’ll come back if I can think of more lol.
Not sure if it’s been mentioned but it’s a good idea to take iron and b12 supplements if you’re cutting down meat and dairy.
