Pepperonata Sauté & Butternut Squash with Romesco Sauce

Pepperonata (peh-peh-roh-NAH-tah) is an Italian vegetable dish of slow-cooked, or stewed bell peppers with onion and garlic.  Of course there are variations and some Italian cooks will add tomatoes, eggplant, or other Italian vegetables.  However you decide to mix it up, classic or uniquely yours, a pepperonata sauté is an excellent topping for proteins or vegetables on a low carb lifestyle and the Romesco Sauce takes it over the top!

Pepperonata & Heirloom squash with Romesco Sauce

We had the luxury of an extra long growing season in Minnesota this year, and I was able to harvest a boatload of different sweet and hot peppers, along with a bountiful harvest of heirloom squash.  It is always easiest to design a dinner around what is in your fridge (or in this case your garden), and the bright orange bell peppers and squash prompted me to think of an Italian fall dinner.  

A little Italian Romesco sauce to spice it up a bit and you have a gorgeous feast rich with the beta carotene from the orange vegetables, and comfort food to the max.

The Basics of a Pepperonata Sauté

The simplest way to make a pepperonata sauté is to cook 2 cloves of minced garlic and 1/2 sliced onion in 1/4 cup of olive oil over low heat for 10 minutes. Season with salt and pepper. Add 5 bell peppers that are quartered and of different colors and cook for 10-15 minutes, until the bell peppers are soft.

For my dinner I added some ground pork, some capers and a bit of anchovy paste.  I opted for a creamy butternut squash as the bed for the pepperonata and Romesco sauce.  The Romesco Sauce is something that we sell online and it is a blend of heirloom tomatoes, peppers, almonds and spices.  It pairs perfectly with squash, as well as many other veggies and meats.
