I got this recipe from a community cookbook years ago - they were trying to raise money to get their community center some new flooring. It was called unstuffed cabbage rolls in the book but we call it just "Cabbage Roll Casserole". Not exactly as good as real cabbage rolls but a really close second if you haven't the time or inclination to fuss with cabbage rolls.
Stuffed Cabbage Casserole - Crock Pot I seasoned the meat with salt, pepper, and garlic, and still added more seasoning to the cooker. I also used whole grain minute rice and canned tomatoes (drained and diced) instead of ketchup.
