Prepare the spicy sauce: heat oil, garlic and green onions over medium heat until soft. Add pineapple juice, chili sauce, vinegar, sugar, soy sauce and salt. Combine the water and cornstarch in a separate container. Mix the cornstarch/water mixture into the sauce and stir over medium-low heat until thickened. You can add more chili sauce if you want spicier spicy chicken sauce. Be sure to taste it as you go so you don’t overdo it. Reduce heat to low.

Prepare the chicken: cut the chicken breast into 1-inch cubes and season with salt. Begin heating the 2 cups vegetable oil over medium-high heat.

Prepare the batter: combine remaining ingredients in a medium bowl and whisk together. Batter should be fairly thin. Place chicken cubes in the batter to coat. Batter should be very thin on the chicken.

Once the oil is heated, reduce heat to medium and add chicken cubes a few at a time, letting the batter drip off before placing in the oil. Let them cook for 3-4 minutes and turn halfway through cooking. Cook until golden brown. Remove and drain on a paper-towel-covered plate. Repeat until all chicken is cooked.

Serve chicken over white or brown rice and cover with plenty of spicy sauce.
