Begin to make mayo veg sandwich by toasting the buttered bread on a griddle or toaster. You can also skip toasting if you Like to save sometime. If you are not serving right away toasting them is a good idea, since it prevents the sandwiches from turning too soggy.

Chop onion and mince garlic. Add them to a bowl. Squeeze in some lemon juice. Allow this to rest for a while until the veggies are ready. This makes the onions & garlic less pungent.

Prepare the veggies by chopping Finley. I have used capsicum and butter lettuce here, you can substitute it with cabbage.

Add mayo, red chilli, flakes, salt, pepper and mustard powder.

Mix up everything well and spread on the bread.

Place another slice and cut to triangles or squares. Serve mayo sandwich.
