Combine salt, pepper, and garlic powder in a shallow bowl with flour then mix well.
Preheat a medium sized frying pan, and melt butter with olive oil for frying. About a tablespoon each.
Dredge the cube steaks starting with the flour mixture, then eggs, and lastly the breadcrumbs. Fry two at a time in pan.
Fry for five minutes on each side. Continue cooking for an additional 8-10 minutes, flipping every so often to avoid overbrowning. Cook until juices run clear, and the pork is no longer pink in the middle.
Serve immediately, or store in an airtight container for up to one week.
