Step 1

Preheat oven to 375 degrees. Lay a large piece of heavy-duty foil on a baking sheet and spray with nonstick spray.

Step 2

Distribute kale onto the center of the foil. Top with bell peppers and water chestnuts.

Step 3

In a small bowl, mix chili sauce, rice vinegar, and garlic. Drizzle over veggies. Cover with another large piece of foil.

Step 4

Fold together and seal all four edges of the foil pieces, forming a well-sealed packet. Bake for 20 minutes, or until veggies are tender.

Step 5

Cut packet to release steam before opening entirely. Season with salt and black pepper, mix well, and enjoy!
