Once you’ve brushed up on your shopping skills, you’ll be ready to make smart and healthy choices time after time.

While the steak provides most of the substance, you can’t forget about all the other great flavors thrown into the mix here. Getting your hands on ripe bell peppers and fresh onions will really kick things up a notch. The assortment of spices involved will also add exciting flavors to each and every bite you take.

As always, this Leaf recipe is super easy to prepare! As you preheat the oven, you can combine the spices and coat the steak. As the steak marinates, you can quickly (but safely!) chop up the veggies into quarter-inch slices. The steak only needs to cook for about 12 minutes. While you may be tempted to dig in right away, be sure to let it sit for a few minutes. Finish off your fajitas with toppings and garnishes and enjoy!
