Tips for Success

With such a simple recipe, it’s all but impossible to go wrong!

  • Slice veggies to similar thickness. To ensure all veggies cook fully and some don’t end up too crunchy or too soft, try to slice them all into equal slices.
  • Adjust the seasonings. Add the seasonings to taste and always start with less. You can always add more but you can’t take it away once you add it!
  • Add your favorite veggies. Feel free to get creative and add in other vegetables to your fajita veggie mix! If you want to kick things up a notch, add in some jalapenos. Mushrooms are also a great addition, especially if you’re making vegetarian tacos!

What to Serve With Fajita Peppers and Onions

Now, how to serve your fajita veggies! There’s the obvious, of course – making vegetarian fajitas – but that’s just the beginning. Here are a few of my favorite ways to serve these quick and easy fajita veggies:

  • Tacos. These make a great topping for tacos of any kind. Add them to chicken or steak tacos or pile them high with other ingredients for easy vegetarian tacos.
  • Scrambled eggs. Stir this into scrambled eggs or make an omelette for a quick and easy breakfast.
  • Salad. For a low-carb option, try making a fajita salad!
  • Sandwich toppings. Add these fajita peppers and onions to burgers, chicken sandwiches, or any other sandwich or wrap for a burst of flavor.
  • Side dish. Or just serve these sauteed veggies up as a quick and easy side to your favorite protein. I think these would be delicious with some grilled steak or chicken!

How to Store Leftovers

Store any leftover fajita veggies in an airtight container in the fridge. They’ll stay good for up to 3 or 4 days in the fridge. I love to add extras to scrambled eggs in the morning or to add flavor to lunch throughout the week. You can enjoy them cold or reheat quickly on the stovetop.
