Don't be put off by the inclusion of frozen chopped spinach - it looked NASTAY, but after reading the comments I figured if people could get their children to eat it, I could probably eat it, too. Honestly, I couldn't even tell it was in there. Just make sure the spinach is pretty finely chopped so you don't get any gross chunks. Plus, spinach is good for you! I heartily recommend using pepper jack cheese (I used weird "Mexican" cheese from the grocery store), otherwise this might be a tad lacking in flavor. Even with the cheese, Jeff found it necessary to drown his in Cholula. I added chopped cilantro to the scallion greens on top. I meant to add mushrooms and bell pepper to the filling, but I forgot. Even though they were sitting ON THE CUTTING BOARD. Jeez.
