"This was easy/fun to make, & it is a picky child-friendly supper! Since we homeschool our sons, it's a great opportunity. Good Eats is often, a nice science lesson, plus a lovely edible experiment!
We changed it around to suit our family. We reduce the amount of salt, & replaced 1/3 of the liquid with water. Better to under salt than over. Take a HUGE baking pan, line it with foil, then each person puts the meat/vegetable combination they want. Add the liquid, & tight foil cover on top, use a chop stick to make a hole on each end to vent. We tripled the ingredients. 2 of my sons used steak strips (Tysons precooked package.) Instead of mirin & red pepper flakes, we substituted hot sauce. We learned the hard way a long time ago, little boys DON'T like biting into pepper flakes! Increase cooking time to 450 degrees for 35mins.
