Take poha in a strainer or bowl and rinse it in clear water with your fingers two to three times. Then keep it aside and do not soak it in water for more than the rinsing time.
Then chop the onion, tomatoes, green chili, and coriander leaves into small pieces.
Heat a pan, add peanuts on a medium flame, and fry them until it has a brown shade on the outside.
When the peanuts have a brown shade outside, transfer them to a bowl.
Now, take the same pan, add 1 tbsp mustard oil with mustard and cumin seeds on medium heat. Let them sizzle for a few seconds.
Add chopped onions and allow them to roast until it has a golden texture outside.
When the onion has a golden texture, add chopped tomatoes. Now allow them to soften; it takes 3 to 4 minutes on medium heat.
When the tomatoes are softened properly then add turmeric and salt.
After that add soaked poha, raisins, peanuts, and green chili.
Mix all the ingredients well and garnish with chopped coriander leaves. Cook it for 3-4 minutes on medium flame.
Now turn off the flame and squeeze lemon juice on it.
Again, mix well. The poha is ready to serve.
