Tear spinach into bite-size pieces, and place in a large bowl. Add onion and mushrooms; set aside. Combine sesame seeds and next 7 ingredients (sesame seeds through garlic) in a jar. Cover tightly, and shake vigorously. Pour over salad; toss well.
This is a staple for our family. The dressing is very delicious.
Awful. When I tried it, all the garlic and sesame seeds just clumped together into an unappealing glob.
