Preheat oven to 350ºF. Line rimmed baking sheet with parchment paper.
If desired, trim ends off zucchini and slice lengthwise so that you have four long halves. Using a spoon, hollow out the middle (take out the seeds) of each half, leaving a little bit on each end to prevent the filling from running out. Place zucchini halves on prepared baking sheet.
In a small bowl, mix together spreadable cheese and diced red pepper. Spread cheese into hollowed out zucchini.
Cover each zucchini with breadcrumbs, and spritz with olive oil. (If you don't have a spritzer, just drizzle as lightly as possible, or spray lightly with non-stick spray.)
Bake for 55 minutes or until zucchini is fork tender and breadcrumbs are golden brown. Cool for 5 minutes before serving.
