INGREDIENTS

• 4 cups cubed seedless watermelon, about 1 1/4 pounds
• 1 pound ripe tomatoes, seeded and quartered or cut into sixths
• 2 to 3tablespoons fresh lemon juice, to taste
• 2 tablespoons extra virgin olive oil
• Generous 1/2 cup chopped celery 
• Sea Salt, to taste
• Freshly ground pepper
• Thin celery slices or sticks for garnish
• Good Quality Feta Cheese, crumbled, for additional garnish 

PREPARATION 

1. Working in batches, purée all of the ingredients, except the celery garnish and feta, in a blender for two minutes or longer until frothy and smooth. Taste and adjust seasonings, making sure you have used enough salt and lemon juice for a vivid flavor. Transfer to a bowl, and chill for several hours. Taste and adjust seasonings. Serve, garnishing each bowl with sprinkles of feta and thinly sliced celery or, if serving in glasses, with a thin lengthwise slice of celery stick.

Tip

• Advance preparation: You can serve this soup the day after you make it. Leftovers are good for two or three days.
