Make sure you have 3 cups cooked rice. If you don’t, cook 1 cup dry rice and cool completely.
Meanwhile, heat a 12-inch stainless steel sauté pan over medium. Add 1 teaspoon oil and swirl to coat. Add 1 pound shrimp and cook, without moving, for 1 minute. Flip and continue cooking until shrimp are opaque and reach 145ºF( 63°C), about 60 seconds more. Transfer to a bowl.
Heat 1 teaspoon oil in now-empty skillet over medium, add 3 beaten eggs and cook until set (yolk and whites are firm) but still wet, about 30 seconds. Transfer to bowl with shrimp.
Toss 1 pound cubed chicken thighs with 2 tablespoons oyster sauce. Heat now-empty skillet over medium; add 1 teaspoon oil and swirl to coat. Add chicken in an even layer and cook, without moving, until golden brown on bottom side, 2–3 minutes. Flip chicken and cook until golden brown on second side and reach 165ºF (74ºC), about 2–3 minutes. Transfer to bowl with shrimp and egg.
In now-empty pan, add 1 teaspoon oil and swirl to coat; once shimmering add 2 cups diced carrots, season with ½ teaspoon kosher salt and cook until tender, about 6 minutes. Transfer carrots to bowl with shrimp and chicken.
Add remaining 2 teaspoons oil to now empty sauté pan over medium heat and heat until shimmering, add scallions whites and light green parts and cook until fragrant and starting to brown, about 1 minute. Add 2 tablespoons minced ginger and 1 tablespoon minced garlic; cook until fragrant, about 30 seconds.
Stir in 3 cups cooked and cooled rice, ¼ cup soy sauce, remaining 1 tablespoon oyster sauce and 2 teaspoons chili crisp, stir to combine then press into an even layer and cook without moving for 2 minutes. Using a thin metal spatula, scrape up rice and stir fry until rice is golden brown, 3–4 minutes more.
Stir in cooked shrimp, egg, chicken, 1¼ cups green peas and 1 teaspoon vinegar; stir fry 2 more minutes. Off heat, stir in 1 tablespoon sesame oil and scallion greens. Serve with additional chili crisp on side.
