Marinated Tomato Salad

Is there anything better than a fresh summer tomato? I think not! In Indiana, we wait all year long for the garden to start producing those big, juicy, sweet tomatoes. My mouth waters just thinking about it.

Dad’s garden usually hits big in the tomato harvest, and I love finding new ways to use them other than BLTs and stewed tomatoes.

Ingredients for Tomato Salad with Potatoes

I would have never thought to add cooked potatoes to my marinated tomato salad until I found this recipe in my cook book from Ireland, titled The Irish Granny’s Farmhouse Potato Recipes.

• Potatoes
• Tomatoes
• Olive Oil
• Dijon Mustard
• Granulated Sugar
• Sea Salt
• Fresh Cracked Pepper
• Fresh chives or fresh parsley, for garnish

But once I tried it for the first time, it makes perfect sense. The potatoes absorb the simple dressing and they really complement the sweet garden tomatoes.

Why this salad is healthy

I love that the potatoes in this simple salad are refrigerated before slicing up to add to the salad. Why, you might ask?

Refrigerating potatoes after cooking increases the amount of resistant starch in the potatoes. This, in turn, improves gut health and helps manage your weight because the starch acts more like a fiber.

Resistant starch also digests slower helping maintain blood sugar.

What a great reason to try this tomato potato salad.
