Depending on the meat used, time to make a stew will be 2 to 4 hours, in order that the meat will tenderize. Yes it can be done, but IMO is a waste of ones outdoor experience time. If you want a good stew, make it at home where you can watch the box or do your taxes while the stew simmers. Then portion and freeze. Take the frozen, insulated packages of stew for the first day, then you only need to reheat to eat. Alternatively, cook at home using suitable sized pieces of food (e.g. ground beef), then dehydrate and carry light for as long as you need before rehydrating and heating. Either way, you get the satisfaction of eating food you prepare yourself, but with an ease of use in camp that gives you time for outdoor activities.
As with all camping type activities, you should try it out at home in your back yard to find out whether you might actually enjoy it when out camping or hiking.
For me, there are enough possibilities for illness on the trail without enhancing it by bringing along PHFs (potentially hazardous foods).
