This looks amazing especially with those potatoes!!
I usually make mine with stew meat, root vegetables like carrots, parsnip and potatoes, and of course, paprika as well as other spices such as caraway seeds. Also added are pinched noodles (csipetke).

I love the way you made this with mushrooms, I never thought to try it that way. Usually only make it with beef or pork stew meat, but will definitely try it with mushrooms!
