Skillet Pierogies with ham and peas

Several weeks ago I had mentioned that I cooked up a large ham, then chopped and froze the leftovers for future meals. Well, earlier this week I used some of that ham when I needed a quick meal. This is one of those "dump" meals that I adjust depending on how many I'm feeding and what I have on hand, but here's a rough recipe:

1-2 boxes Pierogies (use whatever variety you like - I generally go for Potato & Cheddar)
1 medium onion, finely sliced
1 lb frozen peas (sugar snap peas are even better!)
1 c chopped ham (pre-cooked)
1/4 c butter
3-4 Tb parmesan cheese
chicken broth (if desired)

Boil the pierogies until they begin to float then immediately remove from heat and drain. Meanwhile, begin browning onion with butter in a large pan. Add cooked pierogies, and allow them to brown slightly. Next add peas and ham, then cover the pan (but continue to stir every few minutes). After approx 8 minutes, stir in parmesan cheese. You can also add chicken broth at this point if you'd like a moister dish. Allow to cook for several more minutes, adding pepper or a bit of parsley if you'd like. Serve with a green salad and you're all set!
