Obviously you knew that link wouldn't work or you'd naot have
mentioned it. No photo, link is dead... unfortunate because it sounds
good. A half an onion is meaningless as onions come in all sizes...
when I buy onions I look for a bag that contains several sizes, then I
choose one sized for the amount I want... I never use part of an onion
as there is really no way to save a cut onion so that it won't stink
up your fridge and keep it from going all woofy. For a small amount
of onion I usually have a bunch of scallions because I like some in
salads and for Oriental cookery. I also always have a jar of diced
dehy onions, only needs 15 minutes to rehydrate a small amount. And
since your creation contains garlic you'd save time and effort using
shallot.
Rather than cornstarch I'd pour a couple three beaten eggs into the
mix in the already dirtied frypan. I really don't like pie crust, I'd
rather it on toast, a UK muffin, or not. Would be nice to add a diced
bell pepper too. Me, I'd eliminate the boullion, for saltiness I'd
add a cup of diced SPAM.
Rather than Google, Amazon, and other broken/slow methods may I
suggest this for posting pictures:
