We used up two weeks' worth of chard by making a modified Spanakopita! We found a whole wheat phyllo dough and used a "light" butter-like substance spray. It is best served fresh but I have been eating it for lunch as well. I used the leftover phyllo dough to make breakfast quiches with some of the kale, purple basil, etc.
2 1/4 cups minced white onion
3/4 cup minced green onions
3 garlic cloves, minced
9 cups chopped trimmed Swiss chard (about 1 1/2 pounds)
6 tablespoons chopped fresh parsley
3 tablespoons minced fresh mint
1 cup (4 ounces) crumbled feta cheese
1/2 cup (2 ounces) freshly grated Parmesan cheese
1/2 teaspoon salt
1/4 teaspoon black pepper
3 large egg whites
10 (18 x 14-inch) sheets frozen phyllo dough, thawed
Preheat oven to 350°.
Heat a large nonstick skillet coated with cooking spray over medium-high heat. Add white onion; sauté 7 minutes or until golden. Add green onions and garlic, and sauté 1 minute. Stir in chard; cook 2 minutes or until chard wilts. Stir in parsley and mint, and cook 1 minute. Place in a large bowl; cool slightly. Stir in cheeses, salt, pepper, and egg whites.
Place 1 phyllo sheet on a large cutting board (cover remaining phyllo to prevent drying), and coat with cooking spray. Top with 1 phyllo sheet, and coat with cooking spray. Repeat procedure with 3 additional sheets.
Cut phyllo stack into a 14-inch square. Place square in center of a 13 x 9-inch baking dish coated with cooking spray, allowing phyllo to extend up long sides of dish. Cut 14 x 4-inch piece into 2 (7 x 4-inch) rectangles. Fold each rectangle in half lengthwise. Place a rectangle against each short side of dish. Spread the chard mixture evenly over phyllo.
Place 1 phyllo sheet on a large cutting board (cover remaining phyllo to prevent drying), and coat with cooking spray. Top with 1 phyllo sheet, and coat with cooking spray. Repeat procedure with remaining phyllo sheets. Place 18 x 14-inch phyllo stack over chard mixture. Fold phyllo edges into center. Coat with cooking spray. Score phyllo by making 2 lengthwise cuts and 3 crosswise cuts to form 12 rectangles. Bake at 350° for 40 minutes or until golden.
Note: Cut the phyllo stacks so they fit in and up the long side of the baking dish. Arrange folded section against short edges of dish to encase filling.
