Terrific Kale Sandwich
Ingredients
Directions
Make the kale filling
Heat olive oil in a large skillet over medium heat.
Add garlic and cook for about 2 minutes until soft, but not brown.
Add kale, red pepper flakes, capers, and olives.
Add salt if needed, as olives are salty, so be sure to check before adding salt.
Turn kale mixture to coat with oil.
Cover and cook, stirring occasionally, for 15 to 20 minutes.
Serve
Transfer kale mixture to toasted vegan bread slices.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Kale
- Becomes tender while cooking down, forming the bulk of the filling.
- Garlic
- Softens in the oil and adds a savory, aromatic base to the filling.
- Kalamata olives
- Add salty, briny flavor that seasons the kale mixture.
- Capers
- Contribute briny, tangy acidity that balances the rich olive oil.
- Extra-virgin olive oil
- Carries flavor and coats the kale, adding fat and moisture to the filling.
The step that matters
Cover and cook the kale mixture. Cooking covered for 15 to 20 minutes with occasional stirring lets the kale soften and release moisture. Stirring helps the mixture cook evenly so pieces don't scorch on the bottom of the pan.
