Take 1 tablespoon of the butter and heat on a non stick pan. Add the onions and red peppers, along with a pinch of salt, and cook till they begin to get tender. Add the remaining spices, spinach and cilantro and cook just till the leaves wilt. Turn off heat and cool the mixture.
Heat oven to 400F and grease/line 8 muffin cups and keep aside.
Mix the atta (flour), salt, sugar and baking powder. Keep aside.
Beat the remaining butter and the eggs. Stir in the buttermilk and mix well.
Now add the dry mix to the wet, and slowly fold. Do not overmix!
Finally stir in the cheese and the veggie mixture and give it one last mix.
Scoop the batter into the muffin pan with an ice cream scoop (it'll be thick and sticky)
Bake for 16-20 mins till a toothpick comes out clean. I also give it a 2-3 min high broil in the end to really crisp up the tops!
