Using a large skillet, add the olive oil and place over medium heat. Once hot, add the remaining ingredients (black beans, green onions, garlic, Cajun seasoning and hot sauce).

Sauté, stirring occasionally, for 4-5 minutes.

Remove beans from heat and set aside.

Using a small bowl, combine all ingredients and whisk together until well combined; set mixture aside.

Preheat oven to 425°F.

Using a separate skillet, add diced Andouille sausage. Sauté, stirring occasionally, for 8-10 minutes, or until sausage is fully cooked.

Using a medium bowl, combine the Cabot Pepper Jack and Cabot Extra Sharp cheddar cheeses together.

Spread ~⅓ of the chips on a rimmed baking sheet or in an oven-safe shallow dish. Top with ~⅓ of the toppings (cooked sausage, Cajun black beans, cheeses, green onions, jalapenos and tomatoes). Repeat process with the remaining chips and toppings.

Bake for 5-6 minutes, or until cheeses have melted.

Before serving, top with additional sliced green onions and drizzle with Cajun sour cream.
