Preheat oven to 350°F. In a medium bowl, mix together all ingredients except cabbage leaves.

Place 2 Tbsp (30 mL) filling on a cabbage leaf and roll up to secure. Place on a parchment-lined baking sheet, seam-side down. Repeat with remaining ingredients. Bake cabbage rolls in the oven for 15-20 minutes, or until a thermometer inserted into the thickest part reads 160°F (71°C).
