1Shortcuts! Available in freezer section: Frozen mirepoix w/ the onion, celery, & (usually) green peppers. I toss in the whole bag (@ 2-cups).
Also, Morningstar crumbles 'ground beef' substitute is basically seasoned diced mushrooms. If you sub this, add them last & reduce cooking time to just reheat the Morningstar product.
2If going from scratch, all the dicing can be done up to 8 hours ahead; I do the peppers, celery, & onion together & then the mushrooms alone in a large food processor.
3Cook onion, celery, & peppers to your taste preference. Some families prefer these really cooked down, others want them still crunchy. Add mushrooms & saute to the level of tenderness you enjoy. No difference in success of recipe.
4Push above ingredients to sides of pan [or remove from pan/heat] until ground turkey (+) garlic, ginger, & dry mustard is well done.
5Blend all ingredients in pan, add diced water chesnuts and General Tsao sauce. Stir until warm throughout.
6Scoop into iceberg lettuce leaves or serve over bed of chopped romaine
