Sharing is caring!

Tilapia Crostini with Watermelon Salsa are the most delicious, perfect summertime bite you could possibly eat. Not only are these topped with watermelon salsa, they’re topped with GRILLED watermelon salsa.

There’s just something about grilled and smoked foods that make your food magical. It lends a smoky flavor that is unlike anything else, and always reminds me of summertime. 

If sliders had babies…

Aren’t they just precious.

I guess I got tired of regular slider size and had to change my game up. I can’t help it; although I’m a creature of habit, sometimes I have to do things differently. These are crostini sliders, and I’m officially obsessed. I have soooo many ideas for this now that I’ve made these.

Believe it or not, these were made because of this fantastic watermelon salsa I came up with last night after grilling some.

It’s sweet, just slightly spicy, but most of all very fresh.

And summery.

Grilling watermelon brings out the sweetness a little more, and adds that luscious, smoky flavor. You don’t have to; it will still be delicious. 

I honestly cannot get enough of summer.

How To Make Tilapia Crostini with Watermelon Salsa

To begin with, I started with a basic tilapia burger recipe, refrigerated it for about an hour to make sure that the mixture wouldn’t fall apart, and then I browned my tiny patties in olive oil.

While they were cooking, I brushed thin slices of Italian bread with butter and browned them quickly in the oven.

Then, I drizzled a little Stubb’s Green Chile Sauce on the bottoms and topped with tilapia. If you haven’t tried this sauce, you need to by the way.

It’s so good – there are so many things you can do with this stuff.

Stubb’s authentic sauces, rubs and marinades get their bold flavors from real ingredients, with no artificial flavors, colors or sweeteners, or high fructose corn syrup – check out their complete line of rubs, sauces and marinades here.

I topped them with the watermelon salsa and feta cheese.

If you say you don’t like feta cheese, I have to wonder… Have you tried it? For real tried it?? If not, please do me a solid and just try it out.

Feta cheese does a nice job of cutting through the spiciness of the salsa and green chile sauce and gives it a nice salty component.

Although one could argue that this didn’t need two elements of hot, once you taste it you’ll agree that they complement each other very well.

It works because both components are only slightly hot, but their tastes are very different.

….And I do what I want, anyway.

These are perfect for cookouts or dinner parties as a starter, or just to make for fun.

These would also be fabulous served at a bridal or baby shower; or great for a game day!
