In a skillet, add olive oil over medium high heat and add onion and salt and pepper to taste. Cook onions until they are lightly browned, about 4-5 minutes. Add garlic and all the spices and cook for 1 minute. Add the green tomato, vinegar, sugar and 1/4 cup water and bring to a boil and reduce to low and cook stirring occasionally for 15 minutes. Add more water if tomatoes seem too dry. Taste for balance of sweet and sour. Remove and allow to cool.
Meanwhile, preheat the oven to 475. Place the potato wedges on a baking sheet in a single layer and drizzle with olive oil and sprinkle 1 teaspoon Old Bay Seasoning, salt and pepper to taste and toss to coat. Place in oven and roast for 10-12 minutes and turn over and brown on the other side and roast for another 10-12 minutes until potatoes are cooked through and browned. Remove and set aside.
Meanwhile, in a small mixing bowl, add ground beef and half of the cooled green tomato mixture,1 teaspoon Old Bay Seasoning, salt and pepper and mix well. Form 2 patties. In a skillet, add 1 tablespoon olive oil and place over medium high heat. Add patties and reduce heat to medium and cook 4 -6 minutes each side depending on your preferred doneness. Remove patties to a plate and heat skillet to medium high.
Add hamburger buns cut side down to skillet and toast until lightly browned around 1-2 minutes.
To serve: place beef patty on bun and top with chow chow and collard greens and top with the toasted bun. Serve with the oven fries.
