Prepare hollandaise sauce and set aside. I use the Knorr brand.
Slice croissants long way like you are going to make a sandwich. Place them on a cookie sheet. Spread a layer of ham and a layer of turkey on each croissant half. Lay 2-3 asparagus spears on top of the meat. Drizzle as much or as little of the hollandaise sauce on the top of the asparagus. I use all of the hollandaise. Heat until the hollandaise sauce in warm and bubbly. It takes about 15 minutes to heat them up. People go nuts when they eat this.
