FAQs: - **How do I prevent the beans from drying out in the air fryer?** Lightly coat with oil, avoid overcrowding, preheat fully, and cook to tender-crisp, not soft. - **How long does this keep in the refrigerator?** Up to 4 days in an airtight container. Reheat 2 to 3 minutes at 360 degrees Fahrenheit to re-crisp. - **What low-carb sweetener works best as a sugar replacement here?** If you want a faint hint of sweetness to balance the lemon, use a pinch of allulose or a powdered erythritol-monk fruit blend. Both are zero carb and do not spike blood sugar.
