Arugula Salad

I went to a friends house and this salad was served.
Here is how we can make it more alkaline.

Approx. 4 cups of arugula
1 nectarine or peach
1 cup of cherry tomatoes, cut in half
1 cup sliced cucumber
1 avocado, diced
Dress with the juice of one lemon mixed with 3 tablespoons of olive oil.
Season to taste
