Cook bacon in a large nonstick skillet over medium heat until crisp. Remove bacon from pan, reserving 1 tablespoon drippings in pan. Crumble bacon, and set aside. Bring the water to a boil in a large stockpot; add kale. Cook 6 minutes or until tender; drain and set aside. Drain the beans in a colander over a bowl, reserving 1/3 cup liquid.
Heat the drippings in pan over medium-high heat. Add red pepper and garlic, and sauté 3 minutes. Add the crumbled bacon, reserved bean liquid, carrots, sage, and salt; bring to a boil. Cover, reduce heat, and simmer 5 minutes or until carrots are crisp-tender. Uncover and cook 3 minutes or until liquid almost evaporates. Stir in kale; cook 2 minutes.
Warm the tortillas according to the package directions. Spoon 1 cup kale mixture onto each tortilla; top each serving with 1 tablespoon cheese, and roll up.
