First, finely chop all the vegetable and place into a bowl, all together. Next, grate the cheese at this point and keep aside.
In a bowl of all chopped vegetables (beetroot, cucumber, onion, carrot, and capsicum/bell pepper), add red chili powder, cumin powder, black pepper, ketchup, black salt, and salt. Mix well until combined.
Next, take two bread slices and on one slice spread the butter.
And on the other spread the cilantro/mint chutney.
Now, add the veggie mixture on the buttered slice of bread. Spread evenly to form a layer.
Add the grated cheese on top of the veggie mixture and close the sandwich with the other bread slice that's smeared with chutney.
Place the sandwich in a sandwich/panini maker and grill it for approximately 5 minutes or until preferred grilled color/texture appears.
Once done, please the grilled sandwich on cutting board. Cut into slices and garnish some cheese on top.
Serve with chutney or ketchup on the side. Enjoy!
