Prep fast: chop cauliflower and potatoes into bite-sized pieces. Dry them well so they don’t steam in the pan.
Heat a large skillet or wok over medium-high heat. Add oil and swirl. Get it hot but not smoking.
Add potatoes first. Stir-fry for 4–5 minutes until they start to soften. If they’re fighting you, give them a sprinkle of salt to draw out moisture.
Throw in cauliflower, garlic, and ginger. Cook for another 4–6 minutes, stirring often, until both veggies are tender-crisp and lightly browned in spots.
Pour in soy sauce, rice vinegar, and honey if using. Toss to coat evenly and let the glaze reduce for 1–2 minutes.
Add bell pepper and chili flakes if you like a kick. Season with salt and pepper to taste. Remove from heat when peppers stay bright.
Garnish with green onions or cilantro. Serve hot and pretend you didn’t just sprint to the stove—you nailed it.
