I have a spinach hater in my midst and if he knows that there is spinach in something, he turns up his nose at it. However, if it's more well-disguised, he doesn't flinch. This recipe is one of those that you can sneak in some veggies and greens without noticing much. However, if it's a big deal, you can omit it. Remember that it looks like a lot but always shrinks and wilts down to next to nothing!
