Begin by mixing liquid aminos, sesame oil, and chili garlic sauce in a small bowl, and set aside.
In a large non-stick skillet, heat half a tablespoon of sesame oil over medium-high heat. Sauté diced red bell pepper until crisp-tender, about 5 to 7 minutes. Add diced ham and the white parts of the green onions, cooking until the ham is lightly browned. Stir in minced garlic and cook for an additional minute. Transfer this mixture to a bowl and keep aside.
Heat the remaining sesame oil in the same skillet until hot. Add cold rice and cook, stirring occasionally, until thoroughly heated, about 8 minutes.
Push the rice to one side of the skillet and crack the eggs onto the other side. Let the eggs lightly scramble while stirring. Mix the scrambled eggs and the ham mixture into the rice.
Pour the soy sauce mixture into the skillet with the rice and cook, stirring until everything is well combined and hot.
Turn off the heat, then stir in drained pineapple chunks and the green parts of the onions.
Serve hot, garnished with pickled red onion and microgreens.
