I had a ton of cilantro from the garden I didn't know what to do with, so I whipped up this stuff in a few minutes, and it was awesome: 
  
Afghan Coriander Sauce  
  
Ingredients 
  
Fresh cilantro, stemmed (about 1 cup loosely packed leaves)  
3 x Cloves garlic, peeled  
1 x Jalapeno, or other hot pepper, seeded  
1/2 cup walnut or cashews  
1/3 cup Fresh lemon juice OR  
1/3 cup Distilled white vinegar  
1 tsp Salt, or to taste  
1/2 tsp Freshly grated black pepper  
1/4 tsp Ground cumin, (optional)  
2 tbl yoghurt  
  
Liquify in a blender, and serve at room temperature as a sauce for any meat, poultry, or fish dish.
