Combine the olive oil, soy sauce and garlic in a small stir-fry pan. Stir occasionally on medium heat for a minute or two to get the flavors integrating. Add snow peas and broccoli, increase heat to medium-high and stir occasionally for 3–4 minutes. Add the Shiitake mushrooms gill-side down on the bottom of the pan and stir-fry for one minute. Add the Oyster mushrooms, sesame seeds, pecans and sesame oil. Stir-fry for another 2 minutes or so, flipping the Shiitake mushrooms occasionally. Serves 1–2 people for a nice 'snack'. :)
