Method:
Soak sundried tomatoes in hot water to cover for 15 minutes to soften them, then drain and thinly slice.
Meanwhile, bring a large pot of water to a boil for cooking the pasta. In a separate large, high-sided skillet, bring 3/4 cup water to a simmer. Add onion and cook 10 minutes or until tender. Stir in kale, beans and 3/4 cup water. Reduce heat to medium, cover and cook 8 minutes. Uncover and continue cooking 4 to 5 minutes or until most liquid has evaporated, greens are wilted and tender and beans are heated through.
Add pasta to the boiling water and cook according to the package instructions. Add sliced sundried tomatoes 2 minutes before pasta is done. Drain pasta and tomatoes and add to skillet with greens. Stir to combine.
