Step 1

Bring a large pot of salted water to a boil over high heat. Add the pasta and cook until tender but still firm to the bite, stirring occasionally, about 8 to 10 minutes. Drain pasta and transfer to a large bowl. Add the garlic, extra-virgin olive oil, salt, and pepper. Toss to combine.

Step 2

Meanwhile, warm the olive oil in a medium skillet over medium-high heat. Season the salmon with salt and pepper. Add the fish to the pan and cook until medium-rare, about 2 minutes per side, depending on the thickness of the fish. Remove the salmon from the pan.

Step 3

Add the basil, capers, lemon zest, and lemon juice to the spaghetti mixture and toss to combine. Set out 4 serving plates or shallow bowls. Place 1/2 cup spinach in each bowl. Top with 1/4 of the pasta. Top each mound of pasta with a piece of salmon. Serve immediately.
