Make a batter with the eggs and the flour, whisking away any lumps. Season with the salt (and pepper if you wish), and the sesame oil and 1/2 tsp dark soy sauce.
Mix in the vegetables, coating thoroughly with the batter.
Heat 1 tsp olive oil in a large frying pan and coat the base of the pan. Add the batter in 4 small pancakes (more like rostis). Allow to cook through for about 3-4 minutes before flipping.
Make The Sauce
While the pancakes are baking, mix the sauce in a small dish with the ketchup, Worcestershire sauce, honey and 1 tsp of dark soy sauce.
Serve
Once the pancakes are cooked through and golden, serve on a plate and drizzle over the sauce.
