Bring a large pot of salted water to a boil and cook the whole wheat linguine according to package directions until al dente.
While the pasta cooks, heat the extra virgin olive oil in a large skillet over medium-high heat.
Season the shrimp with sea salt and black pepper, then sear in the skillet for 1-2 minutes per side until pink and opaque.
Remove the shrimp from the skillet and set aside, then add the minced garlic, halved cherry tomatoes, and Calabrian chili paste to the same pan.
Sauté the aromatics for 2-3 minutes until the tomatoes begin to soften and the chili paste becomes fragrant.
Reserve 0.25 cup of the pasta cooking water, then drain the linguine.
Add the cooked linguine, seared shrimp, baby spinach, and lemon juice to the skillet.
Toss all ingredients together over medium heat, adding a splash of the reserved pasta water as needed to create a light sauce, until the spinach is wilted.
Garnish the dish with freshly chopped parsley and serve immediately.
