Arugula and Cashew Pesto on Polenta Bites {gluten-free}

Summertime…  And the living is easy. Catfish are jumping, and the cotton is high. Don’t you cry. Stir up these easy green and gold gems–arugula and cashew pesto on polenta bites.

Arugula and Cashew Pesto on Polenta Bites

How about these inviting nibbles for hot summer weather? Simple to make and stress-free to assemble, plus you don’t need to be anywhere near the oven. That keeps summertime living easy.

To make emerald pesto, pulse everything in your trusty food processor—and lick the spatula in 4 minutes. Rock your polenta in the microwave and in 13 minutes it will be hot and thick, ready to spread in a pan to cool.

Including prep and assembly, in 45 minutes, you will be wooing everyone, including yourself, with pesto on polenta gems. They can be yours even sooner if you slice polenta from a shelf-stable tube shaped roll.

Pesto, from the Latin root verb pestare to pound. According to dictionaries, pesto an Italian sauce, made especially of fresh basil leaves, pine nuts, garlic, Parmesan cheese and olive oil. Typically, pesto is stirred into hot pasta.

There is nothing typical about pesto in our gourmet foodie world. We pound pesto from cilantro, mint, broccoli and kale—just about any green veggie. Try replacing basil with spinach to satisfy your fresh pesto cravings in winter. Spicy arugula shines green and garlicky on top of cold and creamy polenta.

Those expensive pine nuts be damned, creative cooks these days mash any crunchy nut we please into pesto, like the barely bitter walnuts in my go-to basil pesto. A quick Google search will lead you to pesto made with pecans, pumpkin seeds, pistachios and almonds. I love the texture of the cashew component in today’s recipe.

Would pesto purists consider it authentic if made with cheese other than Parmigiano-Reggiano? I think not. The rest of us–we try feta. Vegans can leave out the cheese and substiture fresh tangy lemon juice and zest.

Pesto absolutely must include zesty garlic. That’s where I draw the line. Make pesto with any nut, vegetable or cheese you want, just don’t leave out essential garlic.

Thanks Hanneke for inspiring this arugula and cashew pesto on polenta bites. (Warning–the blog includes blaring advertisements—in Italian, that bug the hell out of me. I promise I’ll never put such noise on Letty’s Kitchen.)
