1. To prepare asparagus, mix with onion and saute in garlic and oil about 10 minutes, or until cooked down.
2. Stir in teriyaki sauce. Either mash a bit with a fork or blend for a few quick seconds to get a smoother consistency.
3. To prepare wontons, spoon a small amount of asparagus filling onto one wonton. Take another and seal the two using a fork (I had to wet the edges).
4. Warm sesame oil in pan (last chance to add any other flavors). Saute ravioli about 5 minutes, flipping if you like, and serve! Drizzle some teriyaki sauce on top.
