Invite kids to roll up their sleeves, pat the tofu dry with a few paper towels, and then crumble it into a large bowl for the taco filling.Kids can measure out the chili powder and salt, and then add it to the crumbled tofu. Have them grind in a bit of pepper, too.Tacos are all about assembly, so have kids set up a taco bar by spooning salsa into a bowl and piling shredded cheese on a platter.
