After my wife started growing basil in her garden and we got large crops of basil leaves, this has become one of the family favorites and a regular in our meal rotation. It is 5 ingredients (pork chops, basil, garlic, lemon juice, olive oil) plus salt and pepper, so technically 7, but I think it still counts and is trivially simple to make.

Put the ingredients in a mini food processor (I have a 2 cup processor that works great for this), blend, rub on the pork chops and you can cook on the grill, in a skillet or in the oven. I usually do the oven on a tray with a cooking rack on it. The one simple but time consuming thing that I add that I think makes a world of difference is I brine the pork chops, which keeps them very moist. Just put salt in boiling water to dissolve, add cold water, put in the pork chops and let them sit 2-4 hours in the fridge before the rub and cooking.
