Bring a large pot of salted water to a boil, add pasta, stir, and reduce heat to a low boil. Cook until pasta is al dente, probably about 15 minutes for Fiber Gourmet pasta, but start checking after about 12 minutes. Drain pasta into a colander and let it drain well.
While the pasta cooks, chop up the kale leaves (cutting away the inner ribs if they’re large) and wash the kale in a salad spinner if needed.
Heat the olive oil in a large non-stick frying pan, add the kale all at once, and stir-fry for 2-3 minutes until the kale has wilted and is starting to get tender. Turn off the pan and let the kale cool.
Mix together the fresh-squeezed lemon juice, white balsamic vinegar, and pesto, then whisk in the olive oil to make the dressing.
When the pasta has drained well but is still warm, transfer it to a bowl and stir in about half the dressing.
Let the pasta sit while you cut cherry tomatoes and olives and crumble the Feta.
Stir the cooled kale into the bowl with the pasta.
Add the tomatoes and olives and gently combine; then add more dressing as desired. If you don’t use all the dressing, save it for drizzling over tomatoes or to perk up any leftover salad.
Gently stir in the crumbled Feta, season to taste with salt and fresh-ground black pepper, and serve.
If you don't like to refrigerate salads with tomatoes, this salad still tastes quite good the second day.
