This easy to make, make ahead dish really brings out sweetness of the Bell Peppers.
This is a very flexible dish to make so don't get too caught up in the number of peppers vs onions and Mushrooms - I've even made it with only Mushrooms and Onions.
One or two each of each color Bell Pepper (Green, Yellow, Orange, Red etc.)
One Medium to Large Onion per 4 Peppers
6 to 12 small to medium Mushrooms per 4 Peppers
Good Extra Virgin Olive Oil
Balsamic Vinegar
Some Fresh Italian Herbs, or Dried Italian Herb mix
Using a larger Chef's Knife, cut the peppers vertically into strips.
Remove the outer paper like skin of the onion, remove the top and bottom of the onion and discard the top, bottom and outer skin. Cut the onion vertically into fourths peel the center sections of the quarters away from the outer section about half way between, take the remaining outer sections and cut them in half vertically, making them the approximate size of the middle pieces. So ot slices are too big or too small.
Mushrooms are like sponges so we typically try to clean them without washing them - a goodt Mushroom Brush will accomplish this - brush off any loose material. Set the mushroom upside down on the cutting board and slice them into quarters.
These freshly cut vegetables could easily be served up with dip in this condition, not many people appreciate a raw onion, so we're going to add an additional depth of flavor.
The mushrooms don't get cooked, they can be put in the stainless steel bowl with Oil, Balsamic Vinegar, spices and toss.
When the vegetables are limp, if you haven't already added the spices - do it now. Splash on the Balsamic Vinegar to taste. If you're going to serve the dish now - stir in the mushrooms and serve. If you're making the dish ahead of time, allow the vegetables to cool, add the mushrooms, and put into a container (a gallon sized ziplock bag works great).
This dish can last up to a week in the refrigerator, flip or shake the container daily to coat the contents and distribute the marinade.
For Taste Sake
The leftovers or the prepared dish can be reheated alone or added to a stir fry.
These are wonderful, served along side other appetizers, antipasto like sliced or cubed salami, cheeses, marinated artichoke hearts, anchovies, pickled peppers, and olives.
For Christmas time, consider using only Red and Green Peppers.
