In large pot, sauté marinated chicken thighs in half the butter, until mostly cooked.
Add tikka masala sauce, cooked beans and lentils and bring to a simmer on low heat.
While chili is cooking, make four dosas by heating a large nonstick pan and spreading thin layer of batter to coat.
Cook on one side only until dosa is crisp. Remove from pan, roll and set aside.
In separate nonstick pans, heat remaining butter and fry eggs until whites are set, but yolks are still runny.
To assemble, fill four bowls with chili, top each with fried egg, a little cilantro chutney and garnish with sliced scallions. Serve with dosa on side.
Put rice in bowl, rinse well and cover with 4 cups cold water.
Put urad dal and fenugreek seeds in small bowl; rinse well and add cold water to cover.
Leave both to soak for 4 to 6 hours.
Drain rice and dal-fenugreek mixture in separate colanders. Put rice in a blender. Add one cup cold water and grind to smooth paste. It will take about 10 minutes and may be necessary to work in batches. Repeat process with dal-fenugreek mixture.
In a medium mixing bowl, combine the two pastes. Whisk together, adding enough water to obtain a medium-thick batter. Should yield about 6 cups.
Cover bowl with kitchen towel and set in warm place. Let ferment until surface is bubbly, about 8 hours.
Stir in salt, set aside.
