How To Store / Freeze This Recipe
Allow the grilled vegetables to cool completely before storing. This helps prevent condensation, which can make the vegetables soggy.
Use airtight containers or resealable plastic bags to store the grilled asparagus, red bell pepper, and portobello mushrooms. This will keep them fresh and prevent any unwanted odors from seeping in.
If you plan to consume the vegetables within a few days, store them in the refrigerator. They should stay fresh for up to 3-4 days.
For longer storage, consider freezing the grilled vegetables. Lay them out in a single layer on a baking sheet and freeze until solid. This prevents them from sticking together.
Once frozen, transfer the vegetables to a resealable freezer bag or airtight container. Label the container with the date to keep track of their freshness.
When ready to use, thaw the vegetables in the refrigerator overnight. You can also reheat them directly from frozen by placing them on a baking sheet and warming them in a preheated oven at 350°F (175°C) for about 10-15 minutes.
To maintain the best texture and flavor, avoid microwaving the grilled vegetables as it can make them mushy. Instead, reheat them on the stovetop or in the oven.

Microwave Method: Place the grilled asparagus, red bell pepper, and portobello mushrooms in a microwave-safe dish. Cover with a microwave-safe lid or plastic wrap, leaving a small vent for steam to escape. Microwave on high for 1-2 minutes, checking and stirring halfway through to ensure even heating.
Air Fryer Method: Preheat your air fryer to 350°F (175°C). Arrange the vegetables in a single layer in the air fryer basket. Heat for 3-5 minutes, shaking the basket halfway through to ensure even reheating.
