The day before, I cooked some brown rice and sprinkled it with mirin, sugar, rice vinegar, and salt - to mimic sushi rice. In the morning, I cut up some nori sheets. Then I just layered in rice, nori strips, diced carrots, sprouts, chopped cucumber, and a few chopped green onions. I poured a little soy sauce down the side to hit the sides of the layers but not drench the entire stack.
I meant to put a little pickled ginger at the very top, like the cherry on a sundae, but I forgot; this was, after all, a school morning blur.
I think I sent along homemade cookies as the go-with, but I forget (see above: school morning).
Other ideas to layer in: chopped, cooked sweet potato; sliced avocado dipped in lemon juice; shredded turnip; chopped watercress or lettuce; strips of scrambled egg; baked tofu
And when you look at the top of the jar, you see what a pragmatic, thrifty Mennonite I am. I wonder if this will be the topic of a mother/offspring therapy session one day. . .
