In 1-quart saucepan, mix green beans, soup, bread crumbs, 1/4 cup French-fried onions and the soy sauce. Heat to boiling over medium heat; remove from heat.
Heat oven to 375°F. Separate each can of dough into 4 rectangles. Cut each rectangle into 2 squares. Firmly press perforations to seal.
Spoon 1 tablespoon green bean mixture in center of each rectangle. Fold dough over filling to make triangle; press edges with fork to seal. Brush top of each with melted butter; press extra French-fried onions on top. Place on ungreased cookie sheet.
Bake 18 to 20 minutes or until golden brown.
