Cook your rice. Use short-grain sushi rice.
Slice the the tofu into pieces that will fit into your musubi mold. In a sauce pan, add a little bit of oil and fry the tofu til it browns and forms a nice skin. Repeat for all slices of tofu.
In the same sauce pan, add soy sauce and sugar. Fry until the tofu has soaked up some soy sauce and turned brown.
In a pan fry up the vegan egg alternative. Treat this like a regular egg and fry it up. You will have to slice it to fit in the musubi mold.
Assemble! I recommend a tofu, egg, rice order.
Serve and enjoy!
