Heat oil in a saute pan over medium-high heat. Saute asparagus, shallot, green pepper, and Chinese okra until shallot is translucent, 5 to 7 minutes. Add tomatoes, salt, black pepper, garlic powder, white pepper, chile powder, and cumin. Cook and stir until spices smell toasted, 1 to 2 minutes.

Pour eggs into the pan; cook until edges start to dry, about 2 minutes. Flip mixture over and cook until set, 2 to 3 minutes more. Transfer to a plate and sprinkle Thai basil on top.
