Preheat oven to 350°.
Drain beans in a colander over a bowl, reserving 1/4 cup bean liquid. Set aside.
Heat oil in a large nonstick skillet over medium-high heat. Add onion, and sauté 5 minutes. Add beans, chipotle sauce, savory, and garlic; sauté 5 minutes. Remove from heat. Place 2 cups bean mixture in a large bowl; mash with a potato masher. Add remaining bean mixture, 1/4 cup reserved bean liquid, jicama, and minced cilantro; stir well.
Arrange bell peppers in the bottom and up sides of 4 (10-ounce) ramekins coated with cooking spray. Divide bean mixture evenly among ramekins; place ramekins on a baking sheet. Bake at 350° for 20 minutes. Invert ramekins onto each of 4 plates. Garnish with minced cilantro, if desired.
