Wash and chop the cabbage into bite-sized pieces.
Slice the carrots into thin rounds or matchsticks.
Bring about 1 inch of water to a boil in a pot fitted with a steamer basket.
Add the cabbage and carrots to the steamer basket, cover, and steam for 6 to 8 minutes until tender-crisp.
Transfer the steamed vegetables to a bowl.
Add butter or olive oil, salt, pepper, and minced garlic if using.
Toss the vegetables gently until evenly coated.
Finish with a squeeze of lemon juice or a sprinkle of chopped parsley for extra freshness.
Serve warm alongside chicken, fish, beef, or rice dishes.
