Tangy Tuna-Salad Sandwiches

I find myself eating a lot of tuna for the protein content and the convenience. Here’s a zesty way to prepare tuna salad and beat the monotony.

1/2 cup chopped red bell pepper
1/4 cup bottled pickled vegetables, drained and chopped (such as Vigo Giardinera)
1/4 cup finely chopped red onion
1/4 cup fat-free mayonnaise
1 (12-ounce) can albacore tuna in water, drained and flaked
8 (1-ounce) slices multigrain bread
2 cups trimmed arugula or spinach

Combine the first 5 ingredients in a medium bowl. Spread 1/2 cup tuna salad over 4 bread slices. Top each slice with 1/2 cup arugula and 1 bread slice.
