Heat oil in a large heavy saucepan over medium heat. Add onion and garlic; sauté until tender, 6 to 8 minutes. Add chili powder, thyme, cinnamon, cloves and allspice; sauté 1 minute. Transfer mixture to a blender container; add 1 cup of the broth, tomatoes, cashew butter, chilis and crackers. Cover; blend until mixture is pureed and smooth, at least 1 minute. Return to same saucepan; add remaining broth; bring to a boil over high heat. Reduce heat; simmer, uncovered, 30 minutes or until mixture is reduced to about 3 cups, stirring frequently.
Combine chicken and 2 cups of the sauce in same saucepan; heat through. Add additional mole sauce to taste if desired. Spoon chicken mixture into centers of lettuce leaves; top with cheese and avocado. Refrigerate remaining mole sauce up to 5 days to serve with pork, beef or chicken dishes.
