Make a coarse paste out of boiled corn, butter and oregano and keep it aside.
Heat the oil and saute chopped garlic and chopped coriander stalks (The thick stems which we generally throw has lot of taste and nutrition)
Once garlic is brown add chopped spinach and saute in open with some salt and chilli flakes.
After some 2-3 mins let this cook down and then add chopped coriander leaves and add lemon juice.
Now mix the corn paste into this and then use this mixture as a sandwich filling and put it between two breads.
You can also add some slices of tomato and toast the sandwich on a grill pan and serve hot.
