1.Let cheese sit at room temperature for 10-15 minutes. Cut through top rind and scoop out cheese (rind, too!) with paring knife, reserving hollowed-out rind. Melt and foam butter over medium heat.
2.Add garlic and cook until slightly golden-brown. Add spinach; sauté until tender. Turn to low and mix in scooped-out brie. Stir and fold until creamy.
3.Transfer mixture to hollowed-out rind and let sit a few minutes before serving. Serve with pita chips.
For Pita Chips: Cut each pita bread into 8 pieces, toss in olive oil and cayenne, and bake in 350°F degree oven for 10-15 minutes, or until crisp.
