You can make this with beef rather than pork without adjusting cooking times.
It is very important to use SWEET Hungarian paprika and not hot or smoked. Otherwise, you are going to blow the top of your head off.
I often don't brown the pork, but rather chuck everything into the pot in one go and cook it, and it tastes JUST fine.
If you're having trouble finding tarhonya, try searching for egg barley or egg drop noodles instead (both are alternate names for tarhonya). You can also purchase it online.
If you don't want to bother with tarhonya, you can also serve this over steamed rice or regular noodles like a standard goulash.
If you want to keep this low carb, you can eat it without the tarhonya or over low carb noodles instead.
