I’d been dreaming of one-pan dinners where the entire meal is tossed on a sheet pan and baked. These vegan spicy pineapple and veggie fajitas are exactly that: easy, vibrant, and ready in around 30 minutes. Combine a simple spicy fajita seasoning, toss it with pineapple and vegetables in one bowl, spread everything out on a sheet pan, roast until browned and juicy, then fill warm tortillas with the sweet-spicy mixture. Top with guacamole, salsa, vegan sour cream and cilantro if you like — cilantro really brightens it — and enjoy a new favorite for busy nights.



This recipe is flexible — use whatever vegetables are in your fridge. I often swap in broccoli or other favorites, but don’t skip the pineapple: its sweet-tangy caramelized flavor sets these fajitas apart and turns a weeknight meal into something special.

If you’re not a fan of large bell peppers, mini sweet peppers work beautifully, as I used here. Jalapeños bring heat and a great contrast with the pineapple — omit them if you prefer milder flavors. The balance of sweet pineapple and spicy jalapeño is what makes these fajitas addictive.

These fajitas are naturally vegan, and they’re easy to make gluten-free by serving them with corn tortillas. A quick, sheet-pan dinner that’s both gluten-free and vegan — perfect for busy evenings or casual gatherings.
