Sure, it is really simple. You just have to fry the onions first, until they change color and get glassy and soft. Then you can add mushrooms, carrots, all the hard roots basically, along with the meat, which you should chop up into cubes or other such small sizes. Just fry them all together over low heat, so that you avoid burning all the veggies. After about 10 minutes or so, just add about 500 ml of warm water or broth. Broth is preferable, since it will make your meal more consistent. Broth made of cubes is perfectly fine, but natural broth is much better. Also, the amount of liquid you add, depends on how much stew you want to make and how much veg and meat you want to use. Just add more if you want more stew. And then, finally, you add the potatoes which you should also chop up into small sizes. :Let all of it boil away over medium heat, and occasionally check the potatoes with a fork and see if they got soft and done. Now just whisk in some sour cream and let the whole meal sit for about a half an hour before serving, so all those different tastes combine. Try it out, it is a really easy and awesome meal.
