Most of the calories would be in the egg yolk (55 cal) and the added sugar.

• white radish — more flavor than onion or tomato
• one small tomato
• a tiny onion #can add more
• one egg is tasty, but two would add too much calories. remove yolk if 3 needed
• 金针菇/Enoki — no flavor but quite filling
• — IIF you made a mistake adding too much water
• a teaspoon of sugar for taste,
• some soy sauce or Iodized salt, hopefully to reduce sugar. I prefer soy sauce because I can gauge the dosage by the color
• if water not too much, then the natural flavor or tomato and radish might be sufficient
