4 ounces cream cheese, softened
3/4 cup milk
2 tablespoons all-purpose flour
1/4 teaspoon salt
2 tablespoons Dijon mustard
2-1/4 cups shredded cheddar cheese, divided
2 cups finely chopped fully cooked ham
1/2 cup thinly sliced green onions
Line the bottom and sides of a greased 15x10x1 baking pan with parchment paper; grease the paper and set aside.
In a small mixing bowl, beat cream cheese and milk until smooth. Add flour and salt; mix until combined. In a large mixing bowl, beat the eggs until blended. Add cream cheese mixture; mix well. Pour into prepared pan.
Bake at 375 degrees for 30-35 minutes or until eggs are puffed and set. Remove from the oven. Immediately spread with mustard and sprinkle with 1 cup cheese. Sprinkle with ham, onions and 1 cup cheese.
Roll up from a short side, peeling parchment paper away while rolling. Sprinkle top of roll with the remaining cheese; bake 3-4 minutes longer or until cheese is melted.
