Now it's time to heat things up! Grab your skillet (or skillets, if you're feeling extra fancy) and throw it on the grill. You want it to get scorching hot, so be patient and let it do its thing.
While you're waiting, you can start marinating your steak or chicken. We're talking lime juice, olive oil, and a pinch of cumin - the holy trinity of fajita flavors. Trust us, it makes all the difference.
So, what's the magic number for grilling fajitas? It's all about medium-high heat, baby! You want those veggies to get a nice char on them, and that steak to get a perfect sear.
