Here's the stuff, new and improved. I'm not giving exact measurements, as I never really measured anything for it :P
2 lbs red bliss potatoes, quartered
decent handful of spinach, maybe about 2 cups worth
2 green onions/scallions chopped
bacon bits, about a cup, or cook your own bacon and chop it up, about a half pound
for the dressing, equal parts mayonnaise and sour cream, plus grated parmesan, salt, and black pepper to taste. originally I had used a parmesan peppercorn salad dressing, but I can never find that in the stores, so I made my own. I used about a half caup mayo and sour cream, a quater cup of parmesan, and s+p to taste.
toss the quartered potatoes with some oil, salt, and pepper, spread out on a baking pan, and roast at 400F until they're done. let them cool some, and toss everything together while the potatoes are still a bit warm.
