In a large, deep pan, cook noodles according to the package
Drain the noodles & return to the pan & turn to med-high heat
Add in the onion, butter, & 1/2 of the oil
Let the butter melt & stir to coat
Add in salt & pepper to taste
Let it sit for 5-10 minutes to get a nice golden crust on the bottom
Once the bottom has developed a golden crust, stir the noodles around, add more oil if needed
Let the noodles sit again for a few minutes so more noodles get a golden crust
Repeat until you have your desired amount of crisp to soft ratio
