Place colander in the sink and put your chopped kale in it.
As you pour your cooked pasta over the kale, it will wilt perfectly.
As you wait for your pasta to cook, combine pesto sauce, lemon juice, sundried tomatoes, roasted red pepper, roasted vegetables (may want to reheat them prior to adding), walnuts and nutritional yeast (if using) in a bowl.
Add drained pasta and kale to the bowl and toss to combine.
