Sealed crustless sandwich

A sealed crustless sandwich consists of a filling between two layers of crimp-sealed bread, with the crust removed.

Homemade variations are typically square, round, or triangular; the bread can vary, e.g., white or whole wheat; and the sandwiches can be homemade with common crimping techniques similar to pie crust, ravioli, or dumplings using readily available kitchen tools (e.g., a fork, small spoon or curved knife end to crimp the edges). A purpose-designed "cut and crimp" tool can also be used.

Mass-produced varieties vary in shape, are typically individually wrapped, frozen and packaged—and include proprietary brands as well as house brands. They were introduced in 1995 with peanut butter and jelly filling, followed by numerous patent and trademark disputes as well as numerous competitors entering the market.

The sandwiches offer easily-frozen and thawed, ready-to-eat, portable convenience and have been called, "the Swiss Army knife of foods".
