Place chimichurri ingredients in a food processor and fine chop into a thick sauce.
Place meat in a bowl and season with salt and pepper. Add the chimichurri and combine. Form 6 patties and chill them a few hours for the flavors to combine.
For the toppings, heat a skillet over medium-high heat with oil. Add onions and sweat a minute or two; add cabbage, season with salt and pepper and let wilt 2-3 minutes more. Remove from heat.
Heat a griddle pan or cast-iron skillet over medium-high heat with a drizzle of oil. Add tomatoes, cook a minute on each side then remove to plate. Brush rolls with melted butter and griddle them until toasty and golden, remove to a plate. Add another drizzle of oil and cook patties 8-10 minutes.
