I typically do meal planning and food prep on Sundays to get organized for the week ahead. I make out my ingredient list, then check the pantry and refrigerator to see what I already have on hand. Inevitably, there are always some fruits or veggies on the brink of going bad.

Here are some of my favorite recipes to use up fruits and veggies:

I absolutely hate throwing food away, so I try to get creative using the left over food items, like in my Spinach and Sautéed Veggie Casserole Dish. As I was cleaning out the fridge this week, I realized I had some red bell peppers, orange bell peppers and you yellow bell peppers that I had not used the previous week. So, I decided to make these Simple Oven Roasted Bell Pepper Strips and Onions. They are so delicious and easy to make!

How do I serve the Roasted Peppers and Onions?

This simple vegetarian recipe is so versatile and can be added to a number of dishes or enjoyed all by themselves. The roasted red peppers and roasted onions add a depth of flavor to healthy recipes. They taste delicious on top of fajitas or with my Low Carb Turkey Tacos. Some other ideas would be to serve them over rice, on top of grilled chicken or in a sausage sandwich. 

Can I store the peppers and onions?

Yes, they can be stored in an air tight container in the refrigerator for 3 days. They should not be stored at room temperature. 

Variations to try

Try different varieties of onions

I used red onion to make this dish. However, sweet onions, yellow onions or white onions also work well.

Add different seasoning

The ingredients were kept very simple here, but there are all sorts of ways to dress up this recipe. You could add in a ½ teaspoon of garlic powder to the existing recipe. Italian seasoning would also taste amazing tossed in with the peppers and roasted onions. Or you could even add some fresh basil before serving it.

Use different peppers

Try out different pepper varieties! I think this dish would taste great with poblano peppers or it would be fun to try with mini peppers.
