Well... there's not much to that really. As you know I bought some thyme the other day, so I mixed it with some dried oregano I had and chopped it nice and fine and sprinkled it over the pork loin along with salt and pepper.
I put it in the oven until it had cooked (50 mins?), anyway the juices ran clear. I think the Thai 7 spice that was used in the roasting tin the night before (I lent it to a housemate for his (bland) chicken), kinda rubbed off on the pork while it cooked. Mental note, don't drop Thai 7 spice on your t-shirt, you'll never get it out!
Served with boiled baby new potatoes, onions/garlic/mushrooms and cherry tomatoes.
