Make-Ahead and Storage Tips

Serve chilled with a fork and a lemon wedge on the side. They’re great alongside crackers, toast, or a bed of lettuce. For a light meal, pair with a cold pasta salad or a slice of crusty bread.

Creative Leftover Transformations

Turn extras into something new:

Chop and mix with cooked pasta for a quick tuna salad.
Spoon over avocado halves for a low-carb lunch.
Use the filling in lettuce wraps or pita pockets.

Additional Tips

Add a dash of hot sauce or a pinch of smoked paprika for a flavor twist. If serving for a crowd, use smaller tomatoes or cherry tomatoes for appetizer-sized bites. Don’t forget to taste as you go — balance is key.

Make It a Showstopper

Garnish with finely chopped chives or microgreens. Serve on a chilled platter with lemon wedges and a drizzle of olive oil. Add a light sprinkle of sea salt over the tops for visual sparkle and a burst of flavor.

Spicy Kick: Mix in a dash of sriracha or cayenne.
