Wash the perilla leaves thoroughly and shake off excess water.

Chop 1/4 onion, 2 chili peppers, and 1/4 carrot finely.

Mix the chopped vegetables with 6 tbsp soy sauce, 2 tbsp chili powder, 2 tbsp plum extract, and 1 tbsp minced garlic.

Add 1 tbsp sesame seeds to the seasoning mixture and stir well.

Layer 2-3 perilla leaves at a time and spread the seasoning mixture over them.

Repeat the layering and seasoning process until all leaves are stacked.

Cover with plastic wrap, poke air holes, and microwave for about 2 minutes.
