I made laghman at home last night. It's basically noodles with vegetables. Here's how I made it:
Cook as many thick noodles as you think you'll need. They use homemade noodles that are about a half a meter long here, so you've got plenty of options. I used the thickest dried noodles I could find.
Saute 2 onions in olive oil till soft, then add 6 sliced bell peppers and a few chopped cloves of garlic. Add as much salt and crushed red pepper as you like and let the whole thing simmer till the pepper start letting off some juice. Add a bit of water so there's some liquid with the vegetables.
After draining the noodles, saute them in a bit of oil (getting them crunchy is best if you have time) and serve with the peppers over the top.
