In a large bowl, combine all ingredients (except olive oil) until just mixed.

Shape the ground meat into four equal-sized patties.

Chill the patties in the refrigerator for 15 minutes to prevent crumbling.

When ready to cook, preheat a grill or frying pan over medium heat.

Cook patties for about 5-6 minutes per side, until internal temperature reaches 165°F.

Let rest 5 minutes before serving. Handle patties with care while transferring to plate or bun, as lean meat tends to fall apart easier.
