Here's a freakishly easy and versatile (in my opinion, because my opinion counts...sometimes) recipe. Tahini can be used on sandwiches, it can be a component of hummus, dressing, desserts if you're feeling adventurous, etc...
Below is an unflattering photo:
2 cups sesame seeds
1 large lemon
2-3 cloves garlic
1 tbsp miso paste (optional)
Throw sesame seeds, garlic, salt, pepper, and a little water in a blender. Then lemon zest and juice and blend add water until smooth.
Food factoid: If you want dressing, add chingos of water until it reaches the consistency of salad dressing.
