I reheat a lot of roasted IP veg, or steam them with seasonings. I also grill veg in advance too. You can eat them with our without the lettuce

I also make bigger veg stir frys and portion out the extra veggies for lunch and add my protein to my dinner portions. Pretty much, I make a lot of veg at dinner and have leftovers for lunch.
Are you getting a good variety of veg? That seems to be the key. I can't eat broccoli every day, or mushrooms... etc. I need to vary it. Also, if I ate those veg raw one day, the next time I prepare them they will be cooked.
