Step 1: Prepare the Avocado Ranch - In a mixing bowl, combine the ripe avocado, sour cream, mayonnaise, freshly chopped parsley, freshly chopped dill, minced garlic, Worcestershire sauce, white vinegar, smoked paprika, onion powder, salt, and pepper. Mash and mix until you achieve a creamy consistency. Adjust seasoning to taste and set aside.
Step 2: Mix the Beans and Cheese - In a medium bowl, gently combine the black beans and cannellini beans. Add the freshly grated sharp white cheddar cheese and pepper jack cheese to the beans, mixing until well incorporated.
Step 3: Assemble the Quesadillas - Lay one whole wheat tortilla flat on a clean surface. Spoon a generous portion of the bean and cheese mixture onto one half of the tortilla. Fold the other half over to create a half-moon shape. Repeat with the remaining tortillas and filling.
Step 4: Toast the Quesadillas - Heat a little butter or olive oil in a large skillet over medium heat. Carefully place one quesadilla in the skillet and cook for about 3-4 minutes, or until the bottom is golden brown and crispy. Flip the quesadilla and cook for an additional 3-4 minutes on the other side. Remove from the skillet and repeat with the remaining quesadillas.
Step 5: Serve and Enjoy - Slice the quesadillas into wedges and serve hot with a generous dollop of homemade avocado ranch on the side. Enjoy the creamy, cheesy goodness with a fresh crunch from the herbs!
