Beef strips with carrots and cabbage

I cooked something new yesterday for dinner. Just experimented with what I have in my fridge and just being creative. I only have basic ingredients at home though, but still managed to make my husband a nutritious and tasty meal and didn't even follow any recipes.

Recipe serves 2-3 persons.
To prepare:
beef, cut in strips
1/2 teaspoon pepper
1/2 teaspoon salt
3 tbsp light soy sauce
1 small ginger, crushed
1 clove garlic, crushed
1 small size onion, sliced
1 medium size carrots, diced
juice from 4 pcs calamansi
2 tbsp oil
1-2 cups water

Marinate beef strips for 30 mins to 1 hour in soy sauce and calamansi juice, sprinkling in salt and pepper. Add the crushed garlic and ginger into the marinade.
After marinating, saute garlic and onion in oil. Add beef including the marinade. Add 1 cup water and allow to boil. Add water until beef is tender. Add carrots and the cabbage. Allow to boil for another minute.
