How to Make It
Preheat oven to 350°.
Place quinoa on a jelly-roll pan. Bake at 350° for 10 minutes or until golden brown; cool. Place half of quinoa in a food processor; pulse 30 seconds. Transfer to a large bowl. Add remaining toasted quinoa, almond meal, cornstarch, and salt to bowl; stir to combine. Add oil and egg; stir until mixture is crumbly but holds together when pressed. Press into bottom and up sides of a 4 x 13-inch removable-bottom tart pan coated with cooking spray. Bake at 350° for 15 minutes or until golden and crisp; cool completely on a wire rack.
While crust cools, combine chopped parsley, shallot, black pepper, cream cheese, and goat cheese, stirring until smooth; spread evenly in bottom of crust. Arrange vegetables evenly over cheese mixture; top with parsley leaves. Remove tart from pan; drizzle with balsamic glaze.
