We used to live in South FL and we loved the Canton Steak at Canton Restaurant in Coral Gables. That and the Honey Garlic Chicken! (still haven't got that one right) After we moved away I could never find it at local restaurants so I started experimenting, searching for recipes, etc. This is the version we like. It's not exactly the same but close! Don't let the ingredient list scare you away, it's pretty much just assembling everything and isn't complicated. The snow peas and bell pepper in the veggie mix aren't traditional, but we like them. Reminds me of Miami!
To make the sauce - In frying pan add 1 T oil and minced veggies. Saute until browned. Add rest of ingredients except corn starch. Simmer for 20 minutes, Thicken with corn starch and adjust salt. The veggies will thin it when poured over so make it thicker than you think necessary. Keep warm.
Blanch veggies in 3 c water, 1 tsp oil and salt until al dente, drain. Should only take a couple of minutes. Start this when you put the steak on the grill. Drain well.
Preheat your grill, gas or coals. You want it HOT so you can sear the steak.
Either place a cast iron skillet on the hot grill, or put in a preheated oven, or preheat on top of the stove at the last minute. You want it screaming hot.
Put steak on grill to cook. We cook it to about 125 for med rare, it will continue to cook on the skillet.
When the steak is to your liking, place veggies on the preheated iron skillet, put the steak on top, and pour the sauce over everything.
IF YOU HAVE LEFTOVERS - this makes heavenly beef lo mein - slice the steak, cook thin spaghetti, toss it all together and heat through. Yum.
