Prep your veg so they’re all bite-sized. Mise en place: done. No dramatic surprise chopping scenes later.
Heat oil in a pan on medium heat. Add mustard seeds and cumin seeds; let them crackle for about 20–30 seconds.
Add curry leaves if you’ve got them, then toss in onion. Sauté until it turns translucent and a little caramelized—about 2–3 minutes.
Stir in garlic, ginger, and green chilies. Sreathe in that perfume; it’s allowed to pretend you know what you’re doing.
Sprinkle turmeric, coriander powder, and red chili powder. Stir for 30 seconds to bloom the spices; your kitchen will smell legit.
Throw in the vegetables. Toss well to coat with the spices. Cook on high for 2–4 minutes, stirring occasionally, so they stay crisp-tender.
Season with salt. If you’re using tamarind paste or lemon juice, add a small splash now to brighten things up.
Finish with garam masala if you’re into extra depth. Adjust salt and heat to taste. Serve hot or warm—your call.
