Cut 1 pound pizza dough into 4 pieces; flatten each into a 4-inch square. Cut each square into 4 strips; tie each strip into a knot. Transfer to a parchment-lined baking sheet, brush with olive oil and loosely cover with plastic wrap; let rise 1 hour. Uncover and bake at 400 degrees F until golden, 12 to 15 minutes. Combine 3 tablespoons butter, 2 tablespoons olive oil, 3 minced garlic cloves, 2 anchovy fillets, 1 teaspoon salt and 1/4 teaspoon red pepper flakes in a saucepan over medium heat; cook 1 to 2 minutes. Toss the knots with the butter and 3 tablespoons minced parsley; sprinkle with grated Parmesan.
