Beef Mechado

I'm thinking of cooking beef mechado. I just can't to get beef meat co'z there is none in here (I mean the little house market here in our place).

I went online last to see what I need to buy if in case I'll get to the supermarket.

3 cloves garlic, crushed

1 piece large onion, sliced

2 lbs beef chuck,cubed

8 ounces tomato sauce

3 tbsp cooking oil

1 slice lemon with rind

1 piece large potato, cubed

1/4 cup soy sauce

1/2 tsp. ground black pepper

2 pcs. bay leaves (laurel)

salt to taste 

Here's how to cook it:
Heat cooking oil in a pan then saute the garlic and onion.
Put-in the beef and saute for about 3 minutes or until color turns light brown
Add the tomato sauce and water then simmer until the meat is tender. Add water as needed
Add the soy sauce, ground black pepper, lemon rind, laurel leaves, and salt then simmer until excess liquid evaporates
Put-in the potatoes and cook until the potatoes are soft (about 15 to 25 minutes)
Place in a serving plate then serve hot with rice. Share and Enjoy!
