Read on to learn more about seitan and how to prepare this meal, or click here to jump down to the recipe. 
What is seitan?
Seitan is a wheat based protein source that is very substantial. A three ounce serving of seitan provides 20 grams of protein, similar to the amount of protein found in a similar amount of lean meat, explains this SFgate article.
Thus, seitan is a good protein source for vegetarians and others looking to reduce their meat intake.
We enjoy plenty of meat and fish here, but do like to mix in several meatless meals each week, thus we have seitan with some regularity. Our Seitan Rigatoni with Pepper and Onions is another recipe you might want to try. And this Mushroom Fricassee recipe also features seitan.
I pretty much always find myself cooking seitan along with peppers and onions, it’s a good flavor combination.
Seitan comes plain and with different flavors. This Seitan Skillet with Peppers and Onions uses the plain variety, then we make simple sauce for the seitan. The seitan rigatoni recipe uses Italian style seitan.
Making This Recipe
- Chop up a bell pepper and an onion and get them cooking in a skillet.
- As the onion and pepper softens, whip up a simple sauce using ketchup and soy sauce and few spices.
- Slice the seitan thinly and add it to the skillet along with the sauce. Cook the seitan with the peppers and onions for another 5 minutes to let the flavors combine.
- We added a handful of baby spinach at the end of cooking the dish last time, and it added nice additional color as well as nutrition.
This seitan dish can easily be on the table in 20 minutes or less!
What to serve with this recipe?
I served the seitan skillet with mashed potatoes to round out a substantial meatless meal. This recipe is a good vegan recipe option with plenty of protein.
Wine Pairing
For the most recent time I made this recipe, I opened a bottle of friends.red ($13, 14.2% ABV), a Sonoma red wine blend from Pedroncelli. The wine is an interesting and approachable blend of Merlot, Zinfandel, Syrah and Sangiovese.
I get sage brush on the nose of the friends.red. On the palate, cherry fruit with notes of cedar chest. This is one of our favorite everyday red wines, and is a good match for the seitan.
Another time we had this dish, I served it with a bottle of 2014 Ghost Winery Malbec from Flora Springs Winery ($55, 14.0% ABV). This Halloween themed wine was sent as part of a complimentary sample package by the winery. The Ghost Winery Malbec is made from 100% Malbec grapes. The wine has a nose of violets, menthol and underbrush. I tasted tart cherry and chocolate, a good combination. I sometimes pair Malbec with Mexican or other food with some spice, and it went well with our seitan skillet.

Notes

Thanks to you, I learned something new this morning! I had no clue what Seitan was prior to today – I always get veggie crumbles to use in stes and hash recipes, but now I’ve gotta get my hands on Seitan! By the way, this sounds like such a wonderful, hearty dish!
