Bring saffron and broth to a simmer in a small saucepan (do not boil). Keep warm over low heat.
Heat oil in a large saucepan over medium-high heat. Add shallots; sauté 3 minutes. Add rice, barley, and quinoa; sauté 2 minutes. Add wine; cook 2 minutes or until liquid is nearly absorbed. Stir in 1 cup water; cook 5 minutes or until liquid is nearly absorbed, stirring constantly. Add broth mixture, 1/2 cup at a time, stirring constantly until each portion of broth mixture is absorbed before adding the next (about 25 minutes total).
Remove from heat; stir in cheese and next 4 ingredients (cheese through pepper). Top with asparagus spears, and sprinkle with pine nuts.
