Adjust the cayenne to your liking. The original recipe called for something like 1/2 teaspoon of cayenne, but that's too much for me, never mind the kids. But do put in at least a pinch.
2 Tbsp. canola oil
1/2 tsp. mustard seeds
1/2 tsp. ground turmeric
1 lb. green cabbage, thinly sliced (about 1/2 head)
2 garlic cloves, peeled, smashed with the side of a knife
1 teaspoon salt
1/8 tsp. ground cayenne
Heat the oil in a large frying pan or wok over high heat. When super-hot, add the mustard seeds and cover with a splatter screen or lid to keep the seeds from flying out. When the seeds stop sputtering, add the turmeric, cabbage, garlic, salt, and cayenne. Toss well. Stir-fry until the cabbage is crisp-tender, 2 to 3 minutes.
