Heat a large skillet over medium high heat. Add the oil with the onion and stir. Cook the onion for approximately 7-9 minutes, or until onion is cooked and just starting to caramelize. Stir frequently.

Add the garlic, salt, and Italian seasoning to the onions and stir to combine. Add the Kielbasa to the skillet. Cook the Kielbasa on each side (approximately 3 minutes), or until heated through. Stir the onions frequently, adding 1-2 tablespoons of water to the skillet as needed.

Stir in the chopped bell peppers and green cabbage and stir to combine. Cover the skillet and reduce heat to medium. Cook, covered, for approximately 3 minutes. Uncover, sprinkle with salt and pepper and stir well. Cook until vegetables reach desired doneness.

In a separate bowl, stir to combine the cooked rice and beans, set aside.

Using reusable containers with tight-fitting lids, place approximately 1/2-1 cup of the rice and bean mixture followed by a large chunk of kielbasa, peppers, and onion and purple sauerkraut. Repeat this step until the desired number of containers have been filled (this recipe makes enough for 5 meal prep bowls).
