Peak refuel has a chicken & rice dish that has a bunch of mushrooms...its pretty good
I can't see how boiling in water would not be enough. If they're dried they might cook faster if rehydrated first. Maybe put the shrooms in first for a while, then add the rest of the meal for the required time.
Most wild mushrooms should be cooked over a skillet or in the oven. Some of the chemicals on fungi dissipate with heat. I'm unsure that adding raw dried mushrooms to boiling water would do the trick.
