In a small dish, combined 2 tablespoons of rice vinegar, 2 tablespoons of soy sauce, 2 tablespoons of tomato paste, 2 tablespoons of ketsup, 2 tablespoons of honey and a teaspoon of sesame oil and set aside for now
Bring a large pot of water to a boil
Boil your trimmed green beans for 5 minutes, drain and set aside for now
Slice your sirloin into long thin stripsÂ
In a large bowl, whisk a large egg and add the sirloin and mix until the sirloin is fully coated
Add 1/3 cup of cornstarch and a pinch of salt and black pepper and toss until all of the strips are coated
Place a large skillet or wok over medium to medium high and add a thin layer of a neutral oil
Once the oil is warm, carefully drop individual strips of the coated sirloin into the oil (only add about half of the sirloin to avoid overcrowding the oil)
Fry the sirloin for about 3 minutes or until deeply golden and crispy
Transfer the crispy sirloin onto a paper towel lined plate and repeat the same process with the remaining sirloin
Once all of the sirloin is cooked, reduce the heat to medium, discard any bits from the skillet and add a tablespoon of oil
Quickly sauté the finely minced garlic and ginger for about 60 seconds while stirring consistently
Add the sauce mixture and mix to combine with the garlic and ginger
Add the crispy beef and green beans, toss to combine and let it cook until the sirloin and green beans are warmed through
Garnish with sesame seeds and enjoy!
