In a medium saucepan, combine the sugars and vinegar. Stirring constantly, bring the mixture to a boil and then lower to a simmer. Add the mango, onion, raisins, garlic, ginger, crushed red pepper, cayenne pepper and whole mustard seeds. Continue to simmer for about an hour, or until thick and syrupy. Stir occasionally.

Store the chutney in airtight containers in the refrigerator or can the chutney if you wish.

Preheat a griddle pan or large non-stick skillet over medium heat. Add a tablespoon or so of butter, and melt. Spread mango chutney on one flour tortilla and place, dry side down, on the hot pan. Top with a a few slices of brie cheese, a handful of arugula, and a couple of tablespoons of chicken. Top with a couple more slices of brie cheese and place another flour tortilla that has mango chutney spread on it, on top. Press down. Flip the quesadilla carefully when the bottom is just a little brown, and cook for 2-3 minutes on the opposite side. Remove from heat, and repeat these steps 3 more times.

Cut into triangles and garnish with sour cream and cilantro. Serve with dipping sauces of choice and enjoy!
