Prep the cauliflower rice: If using frozen, squeeze out extra moisture with a clean towel. Drier rice browns better.
Cook the eggs: Heat 1/2 teaspoon oil in a large skillet or wok over medium heat.
Add beaten eggs, scramble just until set, then transfer to a plate.
Brown the protein: Add 1 teaspoon oil. Sear chicken or shrimp until lightly browned and heated through. Remove to the same plate.
Sauté aromatics and veggies: Add remaining oil.
Cook garlic and ginger for 30 seconds. Add chopped veggies (and peas if using) and stir-fry 2–3 minutes until crisp-tender.
Add cauliflower rice: Increase heat to medium-high. Add riced cauliflower and sesame oil.
Spread it out and let it sit 1 minute to lightly brown, then stir. Repeat 2–3 times until steam reduces and texture is fluffy, about 5–6 minutes.
Season: Pour in tamari, rice vinegar, and sriracha if using. Add white pepper.
Stir to coat evenly.
Finish: Return eggs and protein to the skillet. Toss with green onions. Taste and adjust salt, pepper, or tamari as needed.
Serve hot: Top with sesame seeds and a squeeze of lime if you like.
