Prepare your fresh ingredients. Chop garlic, dice onion and slice mushrooms.
Heat up a skillet and melt butter. Wait for it to be hot. Keep over a medium heat setting.
Stir in onion and sauté over a medium to low heat setting. Stir occasionally. The onion should turn slightly golden brown.
Stir in garlic and sauté for another minute or so over a lower heat setting. (or else the garlic will burn on)
Increase the heat to medium and add the sliced mushrooms to the pan.
Mix it it all and sauté. Stir occasionally. The mushrooms will reduce over a medium heat setting. Control the heat, it shouldn't be too low or too high.
Season with salt and black pepper and cook until you are satisfied and it's done.
Take from the heat, garnish with fresh chives or parsley greens if you like. Serve up hot.

Notes
Pick a mushroom. I used regular white button mushrooms. You can use chanterelle too, porcini, shiitake or portobello.
Use white, yellow, or purple onion or shallots. Whichever you prefer.
You may use salted butter too but adjust the salt seasoning.
