Tahini is a sesame paste that is made from toasted and hulled sesame seeds that are ground up to paste.  It’s a condiment often found in Middle Eastern and Mediterranean cuisine and can be found in many of the classic dishes.  Tahini is a main ingredient in hummus and is awesome on a falafel sandwich. Tahini is a super versatile ingredient.  You can use it in baking (think salted tahini chocolate chip cookies, tahini brownies, etc) in salad dressings and marinades.  It’s also great as a veggie dip or swirled into sauces with noodles or spread on toast.  Basically, anywhere you use peanut butter, you can also use tahini.
