I have freeze dried ground beef. Two and a half cups equal one pound.
I do not have milk, so I will add extra water and butter to compensate. I don't buy milk because it goes bad before I can use it.
The noodles get my spaghetti treatment. 6 minutes nuked in a container of water until soft. drain the water, add the rest.
it should work. I have spaghetti as a back up just in case.
edit to add...there is not a lot of noodles to soften up here. and I'm not sure a whole pound of hamburger is needed. I'm start with a mere 4 minutes for the noodles.
4 minutes and the noodles are bigger, but still hard. I'll let then soak for a few. The dead cow flesh will nuke for 3 minutes, that should be fine. Now the instructions call for everything to be added together and most of the time involved to for the noodles to get soft. doing the noodles now will shorten the entire process.
