If you're preparing the samgyupsal party as soon as you arrive home, let the samgyupsal thaw for good thirty minutes. Try to avoid microwaving the frozen samgyupsal since you do not want it thawed in such method as it might affect the tenderness of the meat. If your samgyupsal is unfrozen and fresh, great!
Immediately store the samgyupsal packages in your freezer for future use.
So, let's get this started.
Samgypsal Instruction
1. Wash your hands and all the plates, bowls, and utensils that will be used for the party. Remember to use
chopsticks and not forks. Forks are a no-no in a samgyupsal party. Know your Korean etiquette!
2. Wash your vegetables thoroughly.

You can buy the lettuce in any local grocery market but you might have some difficulty finding the Korean cilantro. The Korean cilantro is not a preferred choice of vegetable to eat along with your samgypsal because of its overwhelming taste. Some people enjoy the unique and powerful taste while others dislike the taste. The Korean cilantro should be on the last place of your grocery list.

The jalapenos can also be bought at any grocery market. However, there are a variety of different options to choose from jalapenos alone. For instance, some are really spicy while others are not. I bought these at a Korean supermarket. The cilantros can be found at your local market. Cilantros are also an option and if you prefer the great taste of it, go get some. I enjoy adding cilantro to every samgypsal party along with gatnip. If you know the English terminology for gatnip, please let me know. The gatnip along with lettuce and cilantro are the three best combination of vegetables I prefer and are recommended to you.

In this photo, you can see the addition of the mushroom sprouts and select mushrooms. The select mushrooms is the most costly vegetable out of the picture. Thus it is an option. If you dine in a Korean restaurant to get samgypsal, a small amount of mushrooms are usually added in along with the plate of meats. The mushroom sprouts that you see on the bottom right corner is also an option. I've tried it the first time when I took this photo as my uncle bought it from the supermarket. It tasted good when you roast it for a quick minute and add it to your 'bite' (described below).
The vegetables are all optional but highly recommended for the party. Lettuce is the priority when it comes to the vegetables. The korean cilantro (don't know the english name for it) that you see on the right is a powerful vegetable and what I mean by it is that its unique taste will overpower the other flavors.
