Preheat oven to 400°, line a rimmed baking sheet with aluminum foil or parchment paper. Lay the bacon on the baking sheet in a single layer. Cook for 5-10 minutes until some grease has formed, you need about 1/4 cup. Chop up the bacon and drain off any excess grease.
Mix together 1 head chopped cabbage, chopped onion, minced garlic, bacon and 1/4 cup bacon grease, oregano, marjoram, salt and pepper. Transfer back onto the pan that you were using to cook the bacon on.
Bake for 30 minutes, stirring once half way through.
