Preheat your oven to 375Β°F.
Bring a large pot of salted water to a boil. Once boiling, add your pasta and cook for approximately 12 minutes, or until al dente with little to no crunch when tasted. Before straining, reserve ΒΌ cup of pasta water. Strain the pasta and set it aside.
Give your vegetables a quick wash where needed, and cut them as shown below.
Toss your diced cauliflower with your marinated chickpeas and transfer them to a lined baking sheet. Roast in the oven for approximately 15 minutes.
When your oven items are halfway done, heat a large pan with a splash of oil over medium-high heat. Once hot, add the diced shallot and cook for about 3 minutes, or until it begins to soften. Add the cherry tomatoes and cook for another 3 minutes, until they also start to soften. Then, add the pasta, lemon & oil sauce, ΒΌ cup of pasta water (or 2 tablespoons of regular water if you forgot to save it), along with the roasted cauliflower and chickpeas. Let everything cook together for 4-5 minutes, stirring occasionally, until the sauce and liquid stick to the noodles and vegetables.
Transfer the pasta to a bowl and garnish with hemp parmesan, diced parsley and pinch of salt and pepper.
