Try lasagna, lentil soup with lots of veggies like carrots and potatoes, sweet potatoes that have been mashed, edamame, vegetarian corn dogs...
Also, a quick little thing to make is an avacado sandwich. Just take half of the avacado, mash it up and throw a dollup in between two pieces of wheat bread and cut out with a cookie cutter to seal the edges. Takes seconds and is packed full of vitamins.
One thing that I do is, at the beginning of the week, I will make up rice, pasta, lentils, steamed veggies, etc and put them all in separate containers. Then, each day, I grab a little out of a few containers and whip something up quick. It's always different and all the containers last me the whole week.
