Preheat the oven to 350 degrees
Trim the bottoms of your asparagus, lay them on a cookie sheet (covered with foil) and drizzle the olive oil over them. Remember: don't go crazy with the olive oil. Sprinkle salt and pepper
Bake them in the oven for about 15 minutes (no longer than 20 min)
If you'd rather blanch your asparagus, see recipe & directions below
I used canned tomatoes because the skin is already removed. Trader Joe's sells seasoned diced canned tomatoes. I heated these (with the tomato sauce) in a pan on the stove and added some balsamic vinegar in there too.
Once the asparagus is finished, remove them from the pan, place on serving plate and drizzle with the balsamic vinegar and other ingredients (tomatoes, walnuts and feta), season with salt and pepper as desired and serve.
