Heat a little oil or ghee in a pan. Add cumin seeds, followed by chopped vegetables like carrots, peas and beans, and sauté for a couple of minutes.
Toss in turmeric, salt and a pinch of asafoetida (hing) for flavour. Stir well to coat the vegetables evenly with the spices.
Pour in 3 cups of water along with 1/4 cup of moong dal (split yellow lentil). Let it cook until the dal softens, then mix in the roasted oats.
Let the oats and dal cook together for 10 minutes, stirring occasionally. Once the khichdi reaches the desired consistency, turn off the heat and serve hot.
