Heat 2tsp oil in a large saute pan; add cumin and mustard seeds and once the seeds start to splutter, add onions and green chili, saute until onions turn translucent, about 4-5 minutes.

Next add mixed vegetables and turmeric, cover and cook until the veggies are tender, about 8-10 minutes.

While the veggies are cooking, soak poha in a big bowl of water for about 1-2 minutes. Drain water  and squeeze out all the extra water and put it in a medium bowl. Season with salt and red chili powder. Set aside until ready to use.

Once the veggies are tender, season with salt and add the poha. Mix well; cover and cook for 2-3 minutes.

Add the lemon juice and mix well. Remove from heat and serve hot immediately.
