That is a average to decent cut of pork, she could have put it in a ziplock with some basic bbq sauce, she could have soaked it in buttermilk ranch and lighty breaded it, she could have used some foil and wrapped it with some fingerling potatoes, she could have just cut it into 1/4 inch filets and put a little butter, soem garlic, some salt and pepper..
And the potatoes, jesus christ you stupid fucking moron. You add a flourish of butter to the potatoes and a bit of shredded gouda adn it would have been so much better than throwing on some probably fridge cold shreds to hot mashed. that's gonna be cold lump of shit.
Take that pork loin (not tenderloin, just pork loin) season it up with salt, pepper, garlic (fresh minced is best of course) rub it in to the meat good on both sides, add some olive oil (if you are smart you'll use the olive oil cooking spray) to the foil and wrap it up loosely. Put that in on 350 for 45 minutes or so. Boil some fingerlings or just some waxy taters on to boil.. cubed up leave the skin on. when they are starting to get soft, pull the pork let it set to rest, then add some cream 1/4 cup ish to the taters and a touch of gouda, softly mash them, you don't want full on soup you want chunks. Then slice and plate pork, and mashed taters. Nothing wrong with a ready made salad mix as well with very light dressing. use the cheddar shreds on that..
