Crumble the feta and spread on a glass pie pan. Sprinkle half of the zaatar over the cheese. Arrange the tomatoes, cut side down, on the cheese. The tomatoes should cover the surface, so use more if necessary. Sprinkle with olive oil and the remaining zaatar. Bake at 450 degrees for 15 minutes; serve warm with toast.

Notes: This works very well with homemade feta.  Any other hard white non-melting cheese such as queso blanco would also work.  Regular, very ripe tomatoes or ripe Italian tomatoes could be used instead of cherry tomatoes if they were seeded.

* Zaatar is a  Middle Eastern condiment.

Zaatar Mix

 1 cup sumac 
 2 cups roasted sesame seeds
 1/2 cup dried ground thyme
 2 tablespoons dried leaf oregano
 2 tablespoons dried leaf marjoram
 2 tablespoons dried leaf savory
 1 tablespoon salt, or to taste (optional)

 Mix all the ingredients together except the salt (some sumac is salty). Taste carefully and add the salt if needed. Keep the zaatar mix in a  tightly closed jar.
