I use an electric sandwich maker but if you don't have one, make them on a tawa.
Bread Slices - 8, white or whole wheat
Carrots - 2 medium, peeled and chopped into small pieces
Peas - about 1/2 cup (I used frozen)
Onion - half of a small one, chopped finely
Green Chillies - 2, chopped finely
Coriander leaves - 1 to 2 tbsp, chopped
Grated Cheese - 1/4 to 1/3 cup (I used pepper jack)
Salt & Pepper - to taste
Butter or Margarine - as required to make sandwiches.
1) Microwave the carrots and peas with little water on high (covered) for 5 to 7 minutes till soft. Allow to cool lightly and mash (can be a bit coarse).
2) Mix the onions, green chillies, coriander leaves, cheese, salt and pepper with this carrot-peas mixture till well integrated (a fork works best). At this point you can refrigerate this or proceed to make the sandwiches.
3) Butter the bread slices on one side. Apply the filling on the un-buttered side and close with another slice. Pop them in the sandwich maker till done and golden brown. Serve warm with some ketchup or as-is.
