Tofu that has been frozen and then thawed before cooking has an incredibly meaty texture. Freeze the tofu in its package. Pull from the freezer, allow to thaw, then wrap the thawed tofu in a tea towel. Place a weight on top and set aside to squeeze out some of the water. The pressed tofu will look like a sponge.
The filling can be cooked the day before. The garnishes prepped earlier in the day. Soften tortillas in the oven a few minutes before serving.
