Penne with Ratatouille

The flavors of this rustic Provençal stew mingle perfectly in the gentle heat of a slow cooker. This recipe yields enough ratatouille for dinner tonight plus leftovers to create two additional meals (see related recipes at left). Let the remaining ratatouille cool to room temperature. Store in airtight containers or heavy-duty sealable plastic bags in the refrigerator for up to 2 days or in the freezer for up to 2 months.
