Cut the bell peppers in half lengthwise. Remove the stem and seeds, then cut into thin strips. Cut the atsuage and pork into bite-sized pieces.
Heat some vegetable oil in a frying pan. When hot, add the pork and stir-fry.
When the surface of the pork turns whitish, add the bell pepper and atsuage, and continue to stir-fry. I think it looks more appetizing if you sort of break the atsuage up as you cook it (at least in my opinion).
Add the dashi stock granules and the oyster sauce to the fried Step 3 ingredients. Finally, swirl in the beaten eggs and toss everything together to finish. I think it's nicest if you turn off the heat before the eggs are completely cooked.
Taste, and season with a little salt if necessary.
