Since moving to our own place in August, Gabby and I have been preoccupied with finding the best ready-to-eat corned beef. We've tried several and for us, the winner is Swift's Juicy Corned Beed in a Pouch.
Retailed at around Php23-24 in groceries and supermarkets, all you have to do is submerge this foil in hot water for 3 minutes then you can eat it. What I do is I wash the entire thing then put it in the rice cooker when the rice is almost cooked. That way I don't have to heat water. Such a lot of savings!
Both me and Gabby likes to eat this with Cheezwiz rice. Yes, that's correct. We put a spoonful Cheezwiz on newly cooked rice to add more flavor to it.
