Remove the stems from the swiss chard. Finely chop one stem and discard the other (one is enough). Finely chop the leaves and set them aside.
In a large saucepan over medium heat, add the olive oil, tomatoes, chopped swiss chard stem, a pinch of salt, and pepper. Cover and sauté for 5 minutes, stirring occasionally.
Add the garlic and cook for 2 more minutes until fragrant. Then add the lemon zest, red chili flakes, pasta, chickpeas, vegetable stock powder, and boiling water. If your pan is a little too small, let the spaghetti soften before stirring it in completely.
Cover and cook for 5 minutes, stirring occasionally.
Add the swiss chard leaves and kale, stirring them in. Cook for another 3 to 4 minutes, checking if the pasta is fully cooked. If not, add a little more water as needed, depending on the spaghetti used.
Turn off the heat, tear the basil leaves by hand, and stir them in along with the lemon juice and parmesan.
Adjust salt and pepper to taste. Serve topped with toasted pine nuts. Enjoy!
