Idlis with grated beetroot a.k.a. "how to get kids to eat their veggies"

Getting the kids to eat their veggies is one of the toughest tasks known to me. Sprinkling it over their dal-chawal helps only to a certain extent- both kids are perfectly capable of not just removing the subji, but also a chunk of dal-chawal with it.
Grating veggies into idli batter is one of the easiest ways to get them to have their veggies. That the idlis also look much better after the addition of veggies is an added bonus.

For the batter
Soak two measures boiled rice and one measure urad dal in separate containers overnight (or at least for 4 hours). Grind rice and urad dal separately in a mixer- keep the rice a little coarse. Mix the ground batter together, whip a couple of times (preferably with your hand), and leave it to ferment for 4 hours (or overnight).

Making the idlis
Add salt to taste, and mix well (taking care to beat air into the mixture). Add half cup grated beetroot, or grated carrots or finely chopped spinach or any other veggie you want to disguise.
Grease idli pans, put the batter, place in the pressure cooker, and steam without the whistle for 10 minutes. If using a microwave, use recommended settings.

You can also garnish with green peas and sliced tomatos to make eyes and a mouth.
