I make this in a vegetarian & a turkey sausage version, depending on my mood & who I'm feeding. It is very simple to make, delicious, cheap & different from a lot of what you see on the table most days. I expanded on the pioneer favourite of fried apples-n-onions, another perennial side or main at my house. The veggie version goes well with ham or pork chops/ribs and is grand beside poultry, venison, or other game.
1Wash, core & slice apples into thinnish wedges, about 8 per half
2Wash & slice sweet potatoes (peel if you like, I usually do not) Slice into rounds about 1/4 inch thick
3Peel onion, halve top to bottom, slice halves 6 to 8 each & loosen into segments
4Warm olive oil in cast iron fry pan (the big one 12" to 14" to hold all ingredients) Add onion on low heat & sweat to anywhere from golden to fully caramelized. 20 minutes. Add sweet potato rounds to browned onions, stir in, cover. Turn the rounds/toss ofter 7 or 8 minutes, when they are browning nicely themselves.
5When potatoes have been turned at least once -- they should be softening -- add the apple wedges to the pan, & put the lid back on for 3 to 5 minutes. You can't ruin this dish, if it goes longer, it's fine. If you like the apples a tad crispy for texture variation, that's fine too. If you like garlic, add a clove or two at this time.
6It's done when you think so. Potatoes tender, apples softened. If you're adding the sausage or kielbasa, cut into rounds add just before the apples & garlic. Grind some pepper over the top when you serve.
