Thai restaurant dish Beef Macadamia sauce? Husb loves. Try as I might I can't find recipe. Think sauce is brown/garlic. Anybody know/have suggestions?

I think the macadamia nut was a substitute for harder to find candlenuts. Anything else in the recipe besides the beef and nuts? Like basil, etc.

1st of all, I *clearly* need to work on my user name. Love both of yours! The beef and cashew nuts does seem pretty close (i had been considering https://www.smooth.com.au/smooth/living/smooth-food/meat-recipes/beef-lemongrass-macadamia-stir-fry w/o the 5 spice or lemon grass) But i think i'll start with the beef/cashew w/o the kap manis, maybe modify with some of the ingreds from this: http://www.geniuskitchen.com/recipe/all-purpose-stir-fry-sauce-brown-garlic-sauce-87748
If it fails I'll grovel at the Thai place. They did tell me how they cooked their tofu one time...
Thank you for your help and thoughts!

My local Thai takeout restaurant offers "Beef Macadamia"
Here's the description I lifted off their website:
Beef Macadamia
Marinated cubes of tender beef stir-fried with mushroom, macadamia nuts, red bell peppers, shredded fresh ginger, scallions and steamed fresh spinach.

Here's a recipe that came up after googling that may help your search:
