Baked Salmon in Foil Recipe

0 Preheat oven to 400°F.
1 Place a large piece of foil on top of a sheet pan. In a mixing bowl, toss chard and chickpeas with vinegar, olive oil, capers, garlic, and salt. Spread out on one half of the sheet pan.
2 Top chard and chickpeas with salmon. Season salmon with some salt and pepper and top with the lemon slices.
3 Enclose salmon and seal foil tightly. (Note: You may have to really compress the chard to fit inside the foil packet. It will seem like a lot, but will cook way down.)
4 Transfer sheet pan with salmon to oven and cook until salmon flakes easily with a fork, 15 to 20 minutes. (This will vary a bit depending on the thickness of your salmon. The salmon is done when it flakes easily with a fork and registers between 125˚F and 145˚F in the thickest part. See note for tips on the ideal temperature for baked salmon.)
5 While salmon cooks, whisk together yogurt, lemon juice, mustard, honey, and a pinch of salt. 
6 Serve creamy lemon sauce over salmon and greens. Enjoy!
