Bring a large pot of salted water to a boil and cook your pasta until just al dente, about 8-10 minutes. Drain and set aside.
While the pasta cooks, drain and rinse your can of chickpeas. Measure out a few for garnish if desired.
In a blender, combine the chickpeas, chopped garlic, lemon juice, olive oil, nutritional yeast, and a pinch of salt and pepper. Blend until smooth and silky, adding water or plant-based milk if needed to achieve a creamy consistency. The mixture should be bright and thick but pourable.
Pour the chickpea sauce into a skillet over medium heat. Warm for 2-3 minutes, stirring gently until fragrant and slightly bubbling.
Add the cooked pasta directly into the skillet with the sauce. Toss gently to coat every piece evenly, allowing the sauce to cling and shimmer on the pasta. Cook for another 1-2 minutes until heated through.
Taste the pasta and adjust seasoning with more salt, pepper, or lemon juice if desired. If the sauce seems too thick, stir in a splash of water or plant-based milk to loosen it.
Transfer the pasta to serving bowls, garnish with reserved chickpeas or fresh herbs if you like, and enjoy immediately while warm and silky.
