Eleven summers ago, I traveled to Tuscany and spent an entire summer studying art.

It was the most magical summer of my life in the most fairytale of settings. And I made the most gorgeous photographs I’ve ever made.

(And that’s saying something. Because I’ve made a lot of images in the 14 years I’ve been shooting.)

Every morning, I crawled out of bed around 7:30, grabbed a slice of pound cake in the kitchen and moseyed my way down the hill to my painting class, which started at 8 a.m. sharp.

After painting, I met my roommates for a cappuccino at the Bar Sport Café, then I’d pick up a few snacks from the fruit stand, speaking broken Italian along the way and playing a few charades, too, to get my point across, before swinging by the grocery for a sandwich.

This sandwich was my life, and I purchased one four days out of five when I was in town. (The other day was dedicated to the pizzeria, where I generally got a slice or two of the eggplant pizza. Because HI, eggplant on pizza is INCREDIBLE.)

Once the sandwich was made, I’d make the trek back up the hill, enjoy my lunch while overlooking the valley below, and then begin work for my afternoon classes.

That was my routine for the weekdays in Cortona, and I have lovely memories enjoying this sandwich while taking in the views.

I mean, just LOOK at that gorgeousness.

In the eleven years since my summer in Tuscany, I’ve come to realize that the thing that made the sandwich was the tuna… and it was because of the olive oil. Go figure.

So today, in celebration of the summertime, I transformed my favorite Italian sandwich into crostini, complete with homemade pesto, fresh mozzarella slices and crumbled olive oil canned tuna.

We gobbled up these crostini… and they’re incredibly simple to make at home, whether you just want a unique lunch or are making an appetizer for party guests.

I’m certainly going to be serving these beauts to guests in the near future, that’s for sure!

  1. I’ve never been a big fan of tuna, but I would totally try this! That pesto tho! Also Tuscany was by far one of the best 4 months of my life, so I can totally relate.

    1. I was always iffy on canned tuna before I spent the summer in Italy. My tune changed then, that’s for sure, and I always get the kind canned in olive oil. That’s my trick. 😉 Thank you! I love that you spent months in Tuscany, too!

  2. These are the perfect little summer appetizer! Only problem is that I wouldn’t be able to stop eating them.

  3. A summer in Tuscany… *sigh* What a great experience, I’m sure! LOVING this appetizer. For some odd reason I’ve been craving tuna lately — great timing with your post – mmm!

  4. What amazing (& delicious!) memories you have of your time in Italy! 🙂 And this crostini sounds amazing! I never thought to pair tuna with pesto, but now I am totally going to try that.
