Instructions
Wash Swiss chard and trim off stems from the leaves. Chop the stems into 1" long pieces. Roughly chop the leaves.
Heat olive oil in large pot with lid or sauté pan with high sides on medium heat.
Add sliced onion and cook until just slightly softened, about 2-3 minutes.
Add the Swiss chard stems and garlic and cook another 1-2 minutes until fragrant.
Add the red pepper flakes (if using) and the lemon zest, stir to combine and cook 1 minute.
Add the chopped Swiss chard leaves and diced tomatoes, cover the pot or pan and cook on a medium-low simmer for about 10 minutes until the Swiss chard has wilted.
Remove the lid, stir to combine and let cook an additional 3-5 minutes.
Turn off the heat, add the lemon juice and stir. Season with salt and pepper to taste.
Serve with a garnish of parmesan cheese if desired.
