Mix together everything thoroughly by hand. The mushroom soup half can undiluted goes in meatloaf. Set aside other half a can for later. You might want to adjust bread crumbs according to how wet meatloaf is after mixed. A little less wet makes it easier to make into a ball for baking. Adding a little extra bread crumbs won't hurt it if necessary.
Oven set to 400 degrees, bake for 1hr 20mins. Always check for doneness as ovens vary.
About 20 minutes before meatloaf done mix other half can of mushroom soup with 1/4c. milk and pour over meatloaf and finish baking. Serve
