Bring a large pot of water to a boil over high heat; add 2 teaspoons of salt to the boiling water, then add the farfalle; cook 7 minutes, or until the pasta is done but still firm.
Drain the pasta in a colander; rinse with cold water, and drain again.
In a big serving bowl, combine the pasta, peas, herbs, garlic, lemon juice, and the remaining 1 teaspoon salt; toss and mix well.
Add the cherry tomatoes; drizzle with the olive oil and toss gently.
Serve or cover and refrigerate until you are ready to serve (the salad can be prepared a day ahead, covered, and refrigerated).
