To marinate the spam, combine 4 tbsp of low-sodium soy sauce, 1 tsp of sesame oil, and honey in a bowl with a flat, wide bottom. Cut the spam into two slices laterally and lay flat in the bowl. Let marinate for 5 minutes on each side.
Add 1 tbsp of canola oil onto a cooking pan and heat over medium high heat. Cook the two marinated spam slices for 2 minutes on each side, or until charred. Remove from heat and let cool. Cut the spam into bite-size cubes and set aside.
To make the eggs, heat 1 tbsp of canola oil onto a cooking pan or a wok over medium high heat. Crack the eggs into a bowl and beat until well combined. Pour the egg onto the wok and let cook for about 30 seconds without stirring. Once the egg starts to be cooked, stir using a spatula for another 30 seconds to 1 minute and lightly break the eggs into smaller pieces. Once the egg is fully cooked, remove from heat and set aside.
To make the fried rice, heat 1 tbsp of canola oil onto a cooking pan or a wok over medium high heat. Add the chopped Chinese celery and stir fry for 30 seconds, then add the chopped green onions. Stir fry for another 30 seconds. Add the steamed white rice and stir gently, while breaking lumps of rice. Add the egg, 4 tbsp of low-sodium soy sauce, 1 tsp of sesame oil, and sugar and mix well until the rice is uniformly covered with the soy sauce, about 3-5 minutes. Add the spam cubes and mix well. Remove rice from heat and serve in a bowl.
