In a medium bowl, combine the tomatoes, basil, garlic, olive oil and half the lemon juiced. Add ½ teaspoon of the salt and the pepper, cover and allow to stand at room temperature 1 hour.
Cook the pasta in boiling salted water to al dente. Meanwhile, peel, pit and chop the avocado. Sprinkle with the remaining salt and drizzle with the remaining lemon half, juiced.
Drain the pasta and transfer to a serving bowl. Toss with the tomato mixture and spoon the avocado mixture over the top. Garnish with the parsley and serve warm.
