In a medium pot of boiled water add chopped asparagus (I added the tops of the asparagus in the last 5 minutes) and boil for 10 minutes, drain and set aside.

In a large pot over medium heat add butter, melt then add flour and salt, combine with a whisk, add milk, 1 cup at a time and continue to stir until thickened, remove from heat and immediately add cubed ham and cheese, stir gently.

In a baking pan (I used a 10 1/2 x 8 1/4 inch, 27 x 21 centimeter deep baking pan) add 4 or 5 small pieces of butter (about 1 tablespoon 14 grams in total) on the bottom of the pan, than layer with lasagna noodles (my size pan used 3 per layer, break if need to fit), then white sauce mixture, (remember everything needs to be divided by 4, more or less), then top with chopped asparagus and sprinkle with grated parmesan cheese, continue for the remaining layers. Bake in 375° (190°) preheated oven, for 20-25 minutes. Let sit 5 minutes, then serve , Enjoy!
