Preheat oven to 400° degrees F.

Mash the hearts of palm with a potato masher in a large bowl. Fold in the Treeline Scallion Flavored French-Style Cheese, cheddar, mayonnaise and ¼ cup chives. Season with the Old Bay, hot sauce and Cajun seasoning, mixing to combine all ingredients thoroughly. Set Aside.

Heat the avocado oil in a medium skillet over medium heat. Once the oil is hot, add the bell pepper, onion and celery, and sauté, stirring frequently, until the vegetables start to just sweat, 6 to 7 minutes. Add the garlic and cook another 1 to 2 minutes. Combine the sauteed vegetables with the hearts of palm mixture in the large bowl, tossing to incorporate all the ingredients. Transfer the dip to a 9x5-inch baking dish and sprinkle the top with the vegan parmesan, then the panko breadcrumbs. Pour the melted butter over the breadcrumbs and bake in the preheated oven, uncovered, until the breadcrumbs are golden-brown and crispy, and the cheese is starting to bubble, 30 to 40 minutes. Remove from the oven and let cool for 5 minutes before serving. Finish the dip with remaining ¼ cup of chives and serve immediately with crackers, pretzels, bread, and additional veggies of choice. Can be served hot or cold! Enjoy!
