I agree with everyone above. There are a lot of nutrients and phytochemicals that you simply can't get in pill form or if you can aren't nearly as good as those found in veggies.
Experiment with different veggies; it doesn't have to be all salads. Hey...even my kids will eat spinach when I cook it with bacon and onions and sprinkle it with parmesan cheese!
I've turned a few brussels sprouts haters into brussels sprouts lovers with bacon, onions and cheese sauce and who could not like broccoli with cheese sauce or green beans almondine with lots of butter?
But please....don't cook your veggies to mush. No veggie deserves such a horrible fate.
