Season the tomatoes with kosher salt and freshly ground pepper.

Broil the tomatoes until the edges brown slightly, about 5 to 10 minutes.

Transfer the broiled tomatoes to a plate.

Place the toasted white sandwich bread slices on the baking sheet.

Spoon the warmed and drained baked beans evenly on top of the toasted bread.

Cover the beans with the broiled tomatoes.

Drizzle Worcestershire sauce over the tomatoes.

Sprinkle the grated sharp white cheddar cheese over the tomatoes and Worcestershire sauce.

Sprinkle chopped scallions over the cheese.
