Boil a large pot of salted water and cook the chickpea pasta according to package directions until al dente.
While the pasta cooks, pat the shrimp dry with paper towels and season with half of the sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the shrimp for 2 minutes per side until they are pink and opaque.
Remove the shrimp from the skillet and set aside on a plate.
In the same skillet, melt the grass-fed butter over medium heat.
Add the minced garlic and red pepper flakes to the butter, sautéing for 1 minute until the aroma is fragrant and the garlic is golden.
Stir in the baby spinach and cook for 30 seconds until it just begins to wilt.
Drain the pasta, reserving a splash of the cooking water, and add the pasta to the skillet.
Add the seared shrimp, lemon juice, and the remaining salt and pepper to the pan.
Toss all ingredients together for 1 minute until the pasta is coated in the silky herb butter sauce, then garnish with fresh parsley and serve.
