How to Make It
Preheat broiler to high.
Split each pita in half horizontally into rounds. Arrange pita rounds on a baking sheet; broil 1 minute on each side or until toasted.
Place oil, rosemary, rind, juice, 1/4 teaspoon pepper, 1/8 teaspoon salt, and beans in the bowl of a mini food processor; process until mixture is smooth.
Cook bacon in a large skillet over medium-high heat about 5 minutes or until crisp. Remove bacon from pan with a slotted spoon; crumble. Add onion and garlic to drippings in pan; sauté 5 minutes. Add mushrooms; cook 4 minutes or until browned, stirring occasionally. Add tomatoes; cook 2 minutes, stirring occasionally. Add kale to pan in batches, stirring until kale wilts.
Spread bean mixture evenly over rough side of pita halves; top evenly with kale mixture. Sprinkle with bacon, remaining 1/4 teaspoon pepper, and remaining 1/8 teaspoon salt.
