Fill half a pot of water and bring it to a boil. Once the water is boiling, add the pasta and follow the cooking directions on the box. While you wait for that, de-pit and scoop out your two avocados into a bowl. Mince 2 cloves of garlic and dump it in. Squeeze some lemon juice and mix until creamy. Cut the grape tomatoes in half, and mince the last clove of garlic. Quickly saute them both in the olive oil on medium heat. Add to the avocado mixture.
Strain the pasta when it's done and add it to the avocado sauce. Mix well, then garnish it  with the Parmesan. Voila!

Notes: Honestly, I really just "eyeball" all my measurements when making this recipe. It can be adjusted completely based on your tastes and, of course, for however many people you may feed. But do keep in mind, this meal does not keep well after. The avocado turns brown fast, so make it fresh and eat it ALL the first time!
