Mix all of the bun ingredients together in a container.

Keep mixing until it thickens up. Pour mixture into a square bowl or container and level it off.

Clean sides if needed. Microwave for 90 seconds and check if it's done.

If not, continue in increments of 15 seconds. Once cooked, remove break from container and slice in half. Put cheese between bun, heat butter in a pan over medium heat, and fry the grilled cheese until you are happy with the texture.
