I came across RV's "Healthy Fast Food" event , Sudeshna's "Cook like a bong" and was thinking about different options and came up with this toast.
White whole grain bread (or Wheat Bread)
Cheese - grated(optional)
The mint and coriander should be taken in equal halves and this should be blended along with green chilli with little water and add salt to the chutney. This chutney can be made before hand and stored in refrigerator. Making this chutney immediately also requires very very less time.
Note: If you don't have mint leaves, you can just use coriander leaves.
Spread a layer of green chutney, place the potato, bell pepper, carrots and Cheese (Optional) on a bread and close it with another bread. Toast this in the toaster. Veggie Sandwich is ready!
