In the U.S. we have food trucks. In India, vendors line the streets with stalls, selling food and wares. Southern and Eastern India use more rice and noodles, but in Northern and Western India wheat products are used as well. Vegetable sandwiches are very popular fare among customers of the street vendors in Mumbai (formerly Bombay), as well as elsewhere, as the trend is spreading. From what I can tell, the trend originated in Mumbai, most likely because of Western influence.
The actual vegetables used may vary from vendor to vendor, but all use mint coriander (cilantro) chutney and chaat masala, and most use either sliced or mashed potatoes. Something I found surprising is that most use white or wheat bread just like we find in stores here, though it makes sense given the application. My twist was to use sliced garlic bread. Most grill the sandwiches, though a few just toast the bread. Common veggies include potatoe (sliced or mashed), onion, beet root, bell pepper, cucumber, cabbage, and tomatoe. Some use cheese, some don't. Google or YouTube "Indian street food sandwich" or just "Indian street food", and you will come up with this sammie and other popular street food options in India.

Mint Coriander Chutney
1 cup fresh mint leaves
1 cup fresh cilantro (aka coriander) leaves
1 or 2 green chiles
1/2 inch ginger
1 tsp cumin
1 - 2 tbsp lemon juice
kala namak (Indian black salt)
Grind in blender until a smooth paste forms, adding a little water if necessary. Note that kala namak isn't actually black, but pink to purplish in color when ground. I found it labeled as "Himalayan" salt.
Masala is simply a spice mix, while chaat masala is a spice mix that includes dried powdered mango. Most vendors mix their own chaat masala according to their individual tastes. If you can't find chaat masala in your area you can make your own, as I did, if you can at least find or make dried mango. Chaat masala has a kind of sweet/sour flavor to it, given by the mango powder, so you might be able to substitute something like tamarind powder instead. If you want to make your own, here are the spices frequently used, which are what I used:
Chaat Masala
dried mango (or amchoor, which is mango powder)
cumin
kala namak (Indian black salt)
coriander seed
ginger
chile powder (I used naga)
asafaetida (also known as hing or fennel)
Grind whatever isn't already in powdered form into a powder. Stir in remaining ingredients.
FD - I'm sure you'll be interested to know that asafaetida is commonly used to reduce flatulence. You might try adding it to whatever you feed Bear (that guy!)
