Slice grapes lengthwise and place into a bowl. Cover with red wine vinegar, about ⅓ cup, and set aside.
Take precooked polenta and slice into thick rounds, about ¾-inch. Cut those rounds into 9 cube-ish shapes. Add to bowl and toss with olive oil, garlic powder, salt, and grated pecorino romano. Place polenta pieces onto a parchment-lined baking sheet and bake for 25 minutes, checking after 15. Remove once they’re golden brown and crispy with a satisfying creaminess inside. Set aside to cool.
Note: If you’d prefer, you may air fry the “croutons” at 425ºF for 12 minutes.
Lower the oven to 375ºF and lightly drizzle olive oil on a baking sheet. Place salmon fillets skin-side down.
Take the crouton pack from your Fresh Express® Pesto Caesar Chopped kit and crush into rough breadcrumbs. In a small bowl, mix together crushed croutons, fresh basil, mayonnaise, lemon zest, olive oil, nuts, and a pinch of salt. Pack onto salmon fillets, coating evenly along the top. Bake for 7 minutes in a convection oven (preferred) or 10-12 minutes in a conventional oven. If desired, place under the broiler for 1-2 minutes for additional browning.
While the salmon bakes, assemble your salad. Strain the grapes (feel free to save the vinegar for a dressing or marinade!) and toss them with the remaining items in your Fresh Express® kit and the polenta croutons. Divide the salad into 2 bowls, top with salmon and a garnish of fresh torn basil, and serve.
