Initially wash all veggies thoroughly. Chop them fine. Here I have ground broccoli into mixie & added ginger & garlic along with it. So finely chopped broccoli cooks quickly. Also boil potatoes & cool them mash with masher. Keep them aside.

In a kadhai Or pan heat 2 tsp oil. Add onions. Stir it until it turns translucent. Now add chopped veggies like French beans, capsicum, broccoli, etc. Stir well until veggies get cooked. I cooked for 7-8 min. Then add red chili powder + coriander, cumin powder +salt, + shahi garam masala + black pepper powder + lemon juice. Cook stuffing along with spices. You may add more masala of your choice. Cover & cook for 5-7 min. Now our stuffing is ready. Keep it aside to cool down completely.

Once cooled well mix mashed potatoes into cooked stuffing. Combine it well. Now let us assemble sandwich. On a wooden plateform spread 2 bread slices. Apply tomato ketchup on one slice also apply green chutney on second slice. Place stuffing on ketchup spread slice. Now cover stuffed slice with chutney slice. Press sandwich gently with fingers so it gets pressed well.

Heat any tawa Or griddle or grill pan. Apply butter over top slice of the sandwich. Place sandwich on heated tawa. Roast well from both sides by applying butter. Roast until sandwich turns crispy. It has nice brown color. Serve ready crunchy sandwich with tomato ketchup or green chutney or as it is.
