How to Make It
In a food processor, combine the garlic with the parsley, basil and oregano and pulse until the herbs are coarsely chopped. Add the capers and pine nuts and pulse until they are coarsely chopped. Add the olive oil and lemon juice and pulse until the pesto comes together but is still chunky. Season with salt and pepper.
In a large bowl, break up the tuna into bite-size chunks. Add the cannellini beans, sliced endives and caper pesto and toss gently until the salad is evenly coated. Season the tuna salad with salt and pepper and serve.
