Oh hi Monday, you’re here again. Do you have your cup of joe? Maybe paired with a big bowl of steaming hot oatmeal with blueberries for breakfast? Me too.

I got back from Nantucket last night and all I wanted to do was prepare a few healthy meals for the week. Personally I’ve found that the trick to maintaining a successful weight loss is to be prepared when it comes to food; always easier said than done though, right? 


ingredients for avocado tuna salad sandwiches

I’m really trying my best to get better at prepping meals, even though I do work from home because I know there will be days where I don’t feel like cooking lunch and need something quick. Of course having a healthy, already made meal in the fridge is a HUGE help. Or basically anything that can be made in less than 10 minutes.

I picked up the habit of meal prepping in college. Each Sunday I’d prepare a few batches of healthy things: homemade oatmeal packets for heating at work, big batches of vegan butternut squash soup (my fav!), high protein snack mixes, baked sweet potatoes and of course, sandwiches. Having these nutritious foods available made it easy to stick to my health and fitness related goals.

These days, I do less prep work because I have a little more time to cook dinner, however most of the time I’m still in need of quick breakfasts & lunches. Breakfasts are usually eggs, or really whatever healthy muffin/bread I’ve baked that week. Lunches are spontaneous and sometimes a challenge, probably because I enjoy eating new, exciting things & making sure it’s high-protein too.

That’s where these avocado tuna sandwiches come in! Over the past few weeks I’ve been loving sandwiches for lunch because they’re filling, easy to make & can be 100% nutritious. When I was asked to partner with the most amazing seafood company, Genova Seafood, to bring you something tasty, I knew that these tuna salad sandwiches were going to happen.

So, let’s talk about this goodness!

Genova Yellowfin Tuna packed in olive oil: Seriously crushing on this tuna. It’s got a tiny bit of olive oil in it so the tuna stays moist & flavorful. It really does make a HUGE difference in flavor and texture. And the lids are easy to open, meaning no can opener is required. P.S. They also make Albacore Tuna packed in olive oil!

Avocado instead of mayo: As you may know, most tuna salad are made with lots & lots of mayo. While mayo isn’t the bad guy, I say why not replace it with heart-healthy mashed avocado instead? There’s more vitamins, fiber & potassium than mayo. Plus avocado is just freaking good.

Fresh cilantro for taste: I’m a huge cilantro fan & adding the herb to the tuna salad made it taste unbelievably fresh. Almost like a guacamole tuna salad. Wait a sec. THAT’S EXACTLY WHAT THIS IS… A GUACAMOLE TUNA SALAD. Omg, yum.

Black beans for fiber & extra protein: A scoop of black beans in the salad provides nearly 6g of protein & fiber. They also add great texture & flavor.

Tomatoes & goat cheese crumbles: Nom nom nom nom nom. That is all.

And of course, if you’re not into bread these days you can enjoy the tuna salad on lettuce wraps, crackers or as is. Over 15g of protein for half of this salad. Now that’s what I call a feel-good lunch ready in less than 10 min. 

Hope you love these! If you make any recipe from AK, I’d love if you’d upload a photo and tag me on Instagram with #ambitiouskitchen. xo!
