Rinse the poha under running water in a colander until it softens. Drain completely and set aside.
Heat oil or ghee in a pan over medium heat.
Add mustard seeds. When they start to splutter, add cumin seeds.
Add the chopped onion and sauté until it turns translucent.
Add turmeric powder and salt. Mix well.
Add the softened poha to the pan and mix gently to combine all ingredients. Cook for another 2-3 minutes, ensuring the poha is well-coated with the spices and vegetables.
Turn off the heat. If desired, add a squeeze of lemon juice for some tanginess.
Garnish with fresh coriander leaves and serve warm.
