Souffle Roll-Up

Directions

1. Line a 15x10x1-in. baking pan with waxed paper; grease the paper and set aside. In a saucepan, combine flour and mayonnaise until smooth. In a large bowl, whisk flour and mayonnaise until smooth.
2. In a large bowl, whisk the egg yolks until thickened; add milk, salt and pepper. Whisk into mayonnaise mixture; cook over medium-low heat until slightly thickened, about 7 minutes. Remove from the heat; cool for 15 minutes.
3. In a large bowl, beat egg whites until stiff peaks form. Gradually fold into mayonnaise mixture. Spread into prepared pan.
4. Bake at 375° for 20 minutes or until golden brown. Run a knife around edges to loosen; invert onto a kitchen towel. Gently peel off waxed paper. Combine the ham, cheese, parsley and onions; sprinkle over souffle to within 1 in. of edges. Roll up from short side. Place on a greased baking sheet. Cover and refrigerate until completely cooled, about 2 hours or overnight.
5. In a blender, combine the parsley sauce ingredients; cover and process until almost smooth. Cover and refrigerate for 1 hour or overnight. In a small bowl, combine mustard sauce ingredients; refrigerate until serving.
6. To reheat souffle, cover and bake at 375° for 40-50 minutes or until heated through. In a small saucepan, heat parsley sauce over medium heat until mixture comes to a boil, stirring constantly; cook and stir 1 minute longer. Cut souffle with a serrated knife; serve with parsley sauce and mustard sauce.
