Delectable Dijon Pork with Apples

I tried something new the other night, and it was fantastic. Not only that, but it was relatively easy and healthy (if you use pork with the fat trimmed off). Feel free to be creative with the veggies and spices. I made it really close to the recipe for the first try, but I think you could be quite creative with this meal.
This is the link to the original recipe: Mustardy pork & apples recipe

Ingredients (that I used, the recipe linked to above is slightly different):

• 5 pork steaks
• 2 tbsp oil
• 2 eating apples, cored and cut into eight
• 1 onion, halved and sliced
• 4 large potatoes, sliced thinly
• small handful sage leaves, torn, or 2 tsp dried
• 1 cup chicken or ham stock (from a cube is fine)
• 1 tbsp Dijon mustard or wholegrain mustard
• 
  

Instructions:

Rub the steaks with olive oil and season with salt, pepper, and herbs and spices to taste. I used Montreal steak spice and garlic. Put into heated large frying pan and fry for 2 minutes on each side until golden brown. Remove from pan, add more oil, and fry the onions, potatoes, and sage for five minutes, then add the apples and fry until apples are slightly softened (about three minutes).

Pour in the stock and spoon in the mustard, then return pork to the pan and simmer until the sauce is reduced by about 1/3 and the pork is cooked through (about ten minutes).

It's a relatively easy one dish meal. Clean up is easy and it heats up great for leftovers! I could see adding peppers or squash to the mix as well, although I did refrain from getting too creative the first time out.

For a vegetarian twist, use tofu and veggie stock.
