Prepare all ingredients as listed.
Cook the rice according to package instructions and keep warm.
Heat a large skillet over medium heat and add avocado oil. Once the oil shimmers, add chicken sausage and cook until browned and heated through, then remove from the skillet and set aside.
In the same skillet, add yellow onion and bell peppers and sauté until softened. Add garlic, ginger, and the white parts of the scallions and cook until fragrant.
Add spinach and cook just until wilted. Return sausage to the skillet and stir to combine, then remove from heat.
In a separate skillet, heat the oil over medium heat and cook eggs to your preference.
Assemble the kimchi breakfast bowl by layering rice, kimchi, the sausage and vegetable mixture, eggs, avocado, green scallions, and black sesame seeds if using.
Combine kiwi, strawberries, and banana in a bowl and sprinkle with chia seeds.
Heat the water to 175–185°F (80–85°C), just before boiling. Remove from heat, add the green tea bags, and steep for 2–3 minutes before removing and discarding the tea bags.
Serve the kimchi breakfast bowl with fruit and green tea.
