Note on vegetables. Should be about 1 cup, more or less of finely chopped vegetables. May omit any, using more of the others to make up for it.
Either:
To a medium-large bowl, add ground beef, the cooled vegetables, and the remainder of the meatloaf ingredients. Toss lightly to combine, take care not to compress the beef. Mixture will be very moist. If possible, refrigerate for an hour to firm up and blend flavors.
Form into eight oval egg-shaped loaves with curved tops (easiest done by estimating half of the mixture, then half again, and so on.) Place on foil-lined rimmed sheet (foil is optional, but makes for easy clean up) an inch or so between each loaf. Glaze with 1/2 the glaze, saving the remainder for when the meatloaves are finished.
When ready to cook, preheat oven to 350 degrees F.
Bake for about 20 to 25 minutes (depending on oven) to reach 160 degrees F. Do not overbake. Small loaves can rise fast in temperature at the end. Remove, drain off the excess drippings, and cover lightly; a inverted sheetpan works great. The temperature should rise to about 165 degrees F; .
Remove immediately from sheet tray; brush off any of the proteins that form around the meatloaf. Add additional glaze before serving. Garnish with green onion and sesame seeds if desired.
Notes:
Glaze:
Mix all ingredients together. Separate the glaze in half, the first portion used when the meatloaves are uncooked, and the second to be used at the end of cooking.
