Spring Wheat Berry & Tuna Salad
Place lettuce in large salad bowl or split between two small bowls.
Add blueberries and strawberries, and toss.
Mix wheat berries, onion and walnuts together in a small bowl. (This can be done ahead and stored in the refrigerator. A drizzle of olive oil may help keep the wheat berries from clumping.)
Top salad with wheat berry mix, tuna pieces and feta cheese, if desired.
In a separate bowl, whisk vinegar and mustard into the olive oil. Add salt and pepper, and toss with the salad.
Time-saving tip: Cook wheat berries over the weekend and store in a container in the refrigerator. Pull out what you need during the week.
