Cut roast in half; place in a 5-qt. slow cooker. In a blender, combine the tomatoes, chili powder, garlic, lime juice, honey, jalapeno and salt; cover and process until smooth. Pour over pork. Cover and cook on low for 8-10 hours or until meat is tender.
Remove roast; cool slightly. Shred pork with two forks and return to slow cooker. Using a slotted spoon, place about 1/2 cup pork mixture down the center of each tortilla; top with avocado, sour cream and cilantro if desired. Fold sides and ends over filling and roll up.
Freeze option: Omit avocado, sour cream and cilantro. Individually wrap cooled burritos in paper towels and foil; freeze in a resealable plastic freezer bag. To use, remove foil; place paper towel-wrapped burrito on a microwave-safe plate. Microwave on high for 3-4 minutes or until heated through, turning once. Let stand 20 seconds.
