M.P.
If he likes mashed potatoes.... try adding squash to it. You can skin it first so there is no other colors and chances are, he won't have a clue it's in there! My kids love it (husband too!). Also, try giving him veggies first. Only offer him his veggies first. If he thinks thats all he has to choose from, maybe he will try some and then of course offer him the rest of his meal : ) Hope this helps!!
