Is your garden overflowing with anything right now? In June and through most of July, I am swimming in squash and zucchini. However, by August the peppers have taken over! We are enjoying fresh bell peppers, sweet peppers and jalapeños with most meals!

We have made lots of stuffed peppers and corn fritters with the peppers on hand, but these Easy Sheet Pan Fajitas have to be one of the simplest ways to use them! I love sheet pan recipes because everything is baked together. This makes clean up a breeze!
