Cut cabbage in quarters, cut out and discard core, and chop cabbage into bite-size pieces.
Melt butter in a large frying pan or saute pan over medium-high heat.
Add cabbage, sprinkle with salt, and add 3 Tbsp. water.
Stir to combine, cover, reduce heat to medium-low, and cook until cabbage is very tender and liquid is absorbed.
Season to taste with salt and serve warm.
