Teasp. Garlic powder
1 crushed red cayenne pepper

1/2 c. Fire roasted tomatoes w/ peppers.  (Canned )

Put yeast, flour, salt, and garlic powder in sauce pan. Slowly add water while stirring over Med. Heat until bubbly. Remove from heat. Add marg till melted, then add tomatoes and lime juice. 
I used fire roasted vegetable corn chips.  Oh so delish!
