Rinse the chicken under cold water and pat it dry with paper towels. Cut the chicken into bite-sized cubes, then transfer it to a bowl. Add the cornstarch and mix with a spoon until each piece is well coated. Set aside.
In a small bowl, mix all the ingredients for the brown sauce together. Set aside.
Heat a wok or skillet over high heat with the oil. Add the ginger and stir-fry until aromatic, followed by the chicken. Stir-fry the chicken until the surface turns white. Add the sugar snap peas, baby carrots, and almonds, then stir to combine well.
Add the brown sauce to the wok or skillet and stir to combine well with the chicken. Once the sauce thickens and the chicken is cooked through, dish out and serve immediately.
Notes
If the sauce is too thick, add a bit water to loosen it up during the stir fry.
