How to Make It
Cook haricots verts per package directions. Remove from package, and plunge into ice water. Drain and pat dry. Cut half of haricots verts into 1 1/2-inch pieces. Reserve remaining half for another use.
Gently toss together chopped haricots verts, pickled vegetables, oil, juice, salt, black pepper, tuna, and olives in a large bowl.
Spread 1 tablespoon hummus inside each pita half; then fill each with about 1/4 cup spinach leaves and 1/2 cup tuna mixture. Top evenly with egg slices.
