This sandwich is a combo of all my favorites...hummus, tomatoes, artichokes,pita bread, and cheese. What's not to love?! I like it both cold or warm, just depends on what I’m in the mood for. Its perfect for a light lunch or cut it into wedges and serve as an appetizer. Make sure you don't bypass toasting the pita bread. I'm not sure why, but it makes all the difference in taste and texture. I've used both commercially prepared and homemade hummus. They both work fine, but if you have the time definitely go with your own mix. Otherwise give Gingerbee's Hummus Amongus (#22060) a whirl...yum! If you don’t have gruyere cheese, any plain old swiss works just fine. Enjoy!
