Best way to get this is in the tutorial level. Start up the tutorial, you can skip the tutorial or complete it. If you skip it you will need to build a furnace so i would just complete the tutorial.
Now go to the village area there should be a pen with two pig in. Kill one and collect the raw porkchop. Then go to your furnace and place the raw porkchop in the top slot and any fuel in bottom slot. The easiest fuel to use would be: coal,charcoal, oakwood or oakwood planks.
Now just eat it
and thats it
