All you need are eggs, spam, cheese, and of course rice. I like to add a bit of sesame oil to it as well.
First, cook your rice - it's the easiest if you have a rice cooker, if not, you can buy the microwaveable kind (the one pictured above is Korean, but I hear they also sell them at Trader Joe's), or you can add a one to one cup of rice to water ratio in a boiling pot, until all of the water evaporates and the rice is cooked and fluffy.
Then cut the spam into little cubes (you can use diced ham if you think spam is disgusting, but I think it’s delicious) and fry it in a pan. When it slowly starts to brown, push it to the side and crack an egg on top of the leftover grease - it's best if it's overeasy, so that the yolk isn't completely cooked and is slightly runny.
Next, put a layer of rice in the bottom of a bowl. Then place two Kraft singles on top, and add another layer of rice, so that you're sandwiching the cheese between the rice. The cheese will slowly start to melt.
Then take the cooked spam and add it on top, drizzle a bit of sesame oil, finishing it off with the egg. You can also added shredded cheese as garnish, or scallions/green onions and even sesame seeds work well.
For an extra kick, you can also mix it with ketchup, or hot sauce. I like to use siracha, or have it with a side of kimchi.
Half way through my bowl!
