Place the black fungus and bean vermicelli in separate bowls and cover each with warm water. Let sit for at least 5 minutes.Rinse the black fungus with clean water, pat dry and mince.
Place the vermicelli in a strainer.
Set a heat-proof bowl inside a large saucepan or stockpot. Add at least two inches of water to the pan, but don’t fill it to more than ½ inch below the lip of the bowl. Remove the bowl, cover the pan, and bring the water to a boil over high heat.
In the meantime, place the strained vermicelli in a heatproof bowl. Crack the eggs into the bowl, add the ramen seasoning and fish sauce, and lightly beat with a fork to break up the eggs. Add the mackerel or sardines and mix well – the mixture should appear muddy.
Add the black fungus, bacon bits, fried shallot, dried shrimp and cheese into the egg mixture and stir to combine.
Once the water is boiling, reduce the heat to low and carefully set the bowl in the pan. Cover the pan and let steam for 30 to 45 minutes. The longer the eggs steam, the harder they get. Serve over steamed rice and seasoned with soy sauce and sriracha.
Stuffed Pepper Variations: No eggs are needed – instead, cut the tops off of two large bell peppers and remove the seeds and membrane. Save the tops of the peppers. Follow the recipe as above up until straining the vermicelli. In a bowl, mix all of the ingredients (minus the eggs) together. Divide the mixture evenly between the two peppers and place the tops back on. Proceed with steaming the peppers by placing them in the bowl set inside the pan and cook, covered, for 30 to 45 minutes.
