Step 1: In a medium bowl, stir together tuna, green onions, mayonnaise, eggs, pepper, and lemon juice. On a lightly floured board, roll half the pastry (1 sheet) into a 12-inch square. Refrigerate the remaining pastry, to keep it cold. Cut into four 6-inch squares. Spoon 2 tablespoons tuna mixture in the center of each square, top with 1 teaspoon tomato, a slice of avocado and 2 tablespoons of jack cheese.
Step 2: Brush edges of pastry with water. Fold one corner over to the opposite side, forming a triangle and enclosing the filling. Seal edges by pressing with tines of a fork.
Step 3: Repeat with remaining puff pastry. Brush tops of the triangles with as much egg glaze as needed to cover.
Step 4: Place rack in bottom third of oven and preheat to 450-degrees.
Step 5: Place turnovers on a lightly greased rimmed baking sheet. Bake for 5-6 minutes, turn and bake 5 or 6 minutes more or until golden on each side. If frozen, bake for 25-30 minutes. Wrap in heavy foil to transport. Best served warm.
