Crumble ground beef in a medium bowl and add salt, pepper, onion powder and garlic powder; mix by hand until seasoning is evenly distributed taking care not to over-work the meat.
Shape ground beef into four hamburger steaks (about 1 inch thick).
Heat vegetable oil in a frying pan over medium-high heat.
Once the pan is good and hot, cook steaks on each side for 4-5 minutes or until nicely seared.
Remove steaks to a plate and set aside (do not worry if they are cooked through, they will finish cooking in the gravy).
Make the gravy:
Reduce frying pan temperature to medium. Add 1 cup Dynasty Brown Gravy Sauce.
Add flour to pan then whisk to incorporate.
Continue cooking and whisking for about 3-5 minutes or until roux is medium brown.
Add beef stock and continue whisking for 2-3 minutes or until gravy starts to thicken a little (gravy will be thin). Add salt and pepper to taste.
Add hamburger steaks to gravy, reduce heat to medium-low then continue cooking, uncovered, for 15-20 minutes or until meat juices run clear and gravy has reduced and thickened.
