Ex 16:13-15
13 That evening quail flew in and covered the camp and in the morning there was a layer of dew all over the camp. 14 When the layer of dew had lifted, there on the wilderness ground was a fine flaky something, fine as frost on the ground. 15 The Israelites took one look and said to one another, man-hu (What is it?). They had no idea what it was.

Quail AND manna.
