Prep the Onions: Slice the onions very thinly and soak them in a bowl of ice-cold water for exactly 5 minutes. Drain the water completely. This is the secret step in this Restaurant-Style Mixed Veg Koshimbir Recipe to keep the onions extra crunchy and remove their sharp bite.
Chop the Veggies: Thinly slice the capsicum, cabbage, and carrot. Ensure they are cut thin and long (julienned) for the perfect restaurant-like texture.
Combine the Salad Base: In a large mixing bowl, add the crunchy, drained onions, sliced capsicum, cabbage, and carrots.
Add Freshness: Squeeze just a little lemon juice (less than half a spoon) over the veggies. Add the freshly chopped coriander leaves along with their tender stems for extra flavour, and mix gently.
Prepare the Spice Mix: In a separate small bowl, combine amchoor powder, regular salt, chaat masala, powdered sugar, spicy red chilli powder, black salt, and Kashmiri red chilli powder. Mix these dry spices very well.
Toss and Serve: Add exactly 1 small teaspoon of your prepared dry spice mix to the chopped vegetables. Toss everything together until the vegetables are well coated with the spices. Your Restaurant-Style Mixed Veg Koshimbir is ready to serve!
