Form bean mixture into 6 even patties to match shape of buns and set aside.
Add 2 teaspoons olive oil to preheated skillet and swirl to coat. Sauté 3 burgers over medium-high heat until crispy, about 3 to 4 minutes per side. If using cheese place on burger patties and allow to melt. Repeat with remaining olive oil and burgers.
Spread bottom bun with 2 tablespoons Raisin Sofrito Ketchup (see recipe below.) Top with cooked burger patty and Creamy Lime Spread (see recipe below.) Enjoy!
Raisin Sofrito Ketchup
Place all ingredients in large measuring cup or blender jar and process/blend to desired texture. (Raisins can be softened with boiling water for a few minutes first for a slightly softer texture.)
Creamy Lime Spread
Combine the sour cream (or mayonnaise), lime zest, lime juice, olive oil and garlic in small bowl. Season to taste with salt and pepper.
