Burgers with green tomato salsa

Ingredients:

• 0.7 kg lean ground beef
• 2 green tomatoes, diced
• Juice of 2 limes
• 1 tbsp. sugar
• 0.5 cup chopped fresh cilantro
• Half a small red onion, diced
• 1 red jalapeño, seeded and finely chopped
• 4 ears of corn, shelled and broken in half
• 2 tsp vegetable oil, plus extra for grilling
• 4 sesame hamburger buns
• 0.5 cups of prepared guacamole

Preparation:

1. Preheat the grill to medium-high heat. Make the salsa. Combine the tomatoes, lime juice, sugar, and 1 teaspoon of salt in a small microwave-safe bowl. Microwave for 2 minutes, then add the cilantro, red onion, and jalapeño.
2. In a large bowl, toss the corn with vegetable oil; season with salt and pepper. Form the ground beef into four 1-inch-thick patties; season with salt and pepper. Lightly coat the grill grate with vegetable oil. Grill the corn, turning occasionally, until tender and charred, about 8 minutes.
3. Meanwhile, grill the patties for about 4 minutes per side for medium-rare. Toast the buns on the grill.
4. Place the patties on buns and top with guacamole and salsa. Serve with corn.
