In large bowl, mix mayo, dressing mix, bacon bits, shredded carrots and onion powder. Chill this mixture while you continue making the rest of the salad. Cook pasta al dente, drain and cool. Fold in pasta carefully. Gently fold in peas last. Chill for several hours and serve chilled or at room temperature. Refresh salad if needed with a tiny bit of mayo, but it usually doesn't need it. Garnish top with more bacon bits pieces. You can never have too much bacon.
