What vegetables can I substitute or add?

I often experiment depending on what’s in my fridge. Bell peppers, zucchini, mushrooms, and onions are my favorites, but I’ve also added cherry tomatoes, asparagus, or even thin carrot slices. Just make sure the vegetables are cut to similar sizes so they roast evenly.

How can I make these fajitas spicier?

If you love heat, I like adding a pinch of cayenne pepper or a few slices of fresh jalapeño to the mix. You can also serve with a spicy salsa or drizzle of hot sauce on top. The key is balancing heat with the natural sweetness of the roasted vegetables.

How do I store leftovers?

I usually store leftover roasted vegetables in an airtight container in the fridge for up to 3 days. When I reheat them, I toss them in a hot skillet for a few minutes to bring back a bit of that roasted texture. Tortillas are best warmed separately.

Can I use frozen vegetables?

I prefer fresh vegetables because they roast better and retain texture, but in a pinch, frozen veggies can work. Just make sure to thaw and pat them dry first, so they don’t steam instead of roast.
