We found this somewhat similar Martha Stewart recipe online and often make it with the oil packed Italian tuna from Costco. We still need to go back to Higher Grounds to benchmark our homemade version against its inspiration.
|In the bottom of a large mixing bowl, combine the vinegar, Dijon, and olive oil with a whisk, then season with salt and pepper to taste. Reserve a few tablespoons of dressing, but leave most of it in the mixing bowl.|
|Add the tuna, lettuce, radishes, and avocado to the large mixing bowl. Toss to coat and combine.|
|Transfer the salad to the serving bowls. Drizzle with additional dressing and capers.|

If preparing this salad in advance to enjoy later, simply store the dressing and salad separately. Hold off on slicing the avocado until the last minute. Combine and toss everything just before serving.
