3 lbs. lean beef, sliced thin
1 cup soy sauce
1/2 cup kalamansi juice or lemon juice
2 tablespoon garlic, crushed
1/4 cup sugar
salt and ground pepper to taste
1 large onion, sliced thin
1/2 cup canola oil
Mix soy sauce, lemon juice, garlic, sugar, salt and pepper. Add beef. Marinade for at least 30 minutes in the fridge. After 30 minutes remove the beef from the marinade and drain remaining juice. Make sure to set aside the remaining marinade.
Heat pan and add cooking oil. Start frying beef till golden brown and set aside. Using the same oil brown slices of onions and set aside. Using the same pan pour remaining marinade and simmer for few minutes. Once the sauce starts to thicken add the browned beef to the pan and continue to simmer for few more minutes. Add the brown onions, mix and remove from heat and serve
