Saute keilbasa and onions on high heat until nicely browned.
Dump in a metric tonne of cabbage and a good pour of fresh water and let the cabbage steam through.
While you still have some water in the pan, add a couple tablespoons of Vogue Veggie Base broth powder, and salt. Swirl the powder into the liquid.
Near the end, add the tomatoes – they just need to cook enough to get warm, really.
The whole thing took like 5-10 minutes – just turn the burner on high and go to work! :-)
