Trust me - these poblano shells are going to change the bell pepper game. They are a little smoky and incredibly flavorful, especially because they are stuffed with all my fav taco fixings, some of my favorite Bumble Bee® Solid White Albacore in Water and topped with CHEESE. OMG you guys - promise you’ll be obsessed. We’re gonna do these on IG live in a few weeks - they are just too good not to share!

Ounce for ounce Bumble Bee® Tuna is lower in calories, fat, sat fat, and the cholesterol levels are leaner than the leanest cuts of beef and chicken. It’s the perfect way to get a quick and easy dinner on the table plus plenty of healthy protein. And you might as well make a double batch because these do great in the fridge and make for excellent leftovers. The quinoa bulks up the filling a little bit and adds extra protein. But if you’re not a quinoa kinda fam, feel free to use white or brown rice. Equally as delish (and same ratio of uncooked rice to quinoa).

    This is one of my Gaby favs! A staple at my house 🙂

    Question Gaby: Do you think you could assemble and then freeze in a glass dish and bake at a later time?

  2. This recipe turned out so great! My boyfriend is a crazy person and doesn’t like “stuffed” peppers even though he likes peppers, so we make these as “unstuffed peppers” and just cook everything on the stove. It saves the time it would’ve taken in the oven and I still get to make the recipe 😀

    I bought tuna for this recipe and it took me weeks to build up the courage to try it because I don't normally like tuna...I've since made these 3 times with the tuna and they are amazing! Even if you don't like tuna, you will love these.
    But I always struggle to think of what else to make with them as a side. Any suggestions?

    Thank you!
