In a pot, boil some water, and add salt to it. Add the peanuts, slightly cover the pot (to let the steam escape through), and cook them for 10 minutes on high flame.
Seive away the water from the pot, and let the peanuts cool down at room temperature.
Take a bowl, and add chopped cucumber, tomato, onion, bell peppers, green chilies, red chili powder, chaat masala powder, lemon juice, and salt. Lastly, add the peanuts as well.
Now, cover the bowl with a lid or a plate, and toss it vigorously for 30 seconds till all the ingredients are mixed well.
Your peanut salad is ready to be served.
