Fill a large pot about halfway with hot water (from the tap); cover with a lid and bring to a boil over high heat.
Wash and dry the fresh produce. (Skip the spinach if it came pre-washed.)
2 red bell peppers
4 tomatoes
1 (5 oz) pkg baby spinach
If using frozen shrimp, place them in a colander and run under cold water to thaw them slightly and remove any ice crystals. (If using fresh shrimp, skip this step.) Place the shrimp on a clean towel or paper towels and pat dry.
1 ½ lb raw peeled shrimp, fresh or frozen
When the water in the pot comes to a boil, uncover the pot and season the water with salt, then add the pasta and stir for a few seconds. Cook the pasta, uncovered, for 11-12 minutes (or according to package directions). Once done, drain the pasta in a colander.
10 oz linguine pasta
2 tsp salt
Peel and chop onion into 2-inch pieces; peel garlic. Spread out on a baking sheet.
1 medium red onion
4 cloves garlic
Cut the bell peppers lengthwise; remove and discard the seeds and white membrane and chop into 2-inch pieces. Chop tomatoes into quarters and place on the baking sheet along with the peppers.
Drizzle veggies with oil and season with salt and pepper; place in the oven and roast for 13-14 minutes. During that last 3-4 minutes of cooking, change the setting to broil and cook until they begin to char slightly.
2 tsp extra virgin olive oil
½ tsp salt
½ tsp black pepper
Meanwhile, heat a skillet over medium-high heat. Once the skillet is hot, add butter and swirl to coat the bottom.
2 tsp butter, unsalted
Add shrimp to the pan, season with salt and pepper. Cook until golden brown and pink all the way through, about 2-3 minutes.
2 tsp salt
2 tsp black pepper
Finely grate Parmesan.
4 oz Parmesan cheese
When vegetables are done cooking let cool for 3-4 minutes. Once cooled, peel the skin off the peppers and tomatoes and discard them.
Add vegetables to the blender and blend until mostly smooth. Add half the Parmesan and season with salt and crushed red pepper. Pulse to combine.
½ tsp salt
½ tsp crushed red pepper
Return pasta to the pot, add shrimp, sauce and spinach and stir to until spinach is wilted slightly.
To serve, divide pasta between plates, top with remaining Parmesan. Enjoy!
