How to Make It
Step 1
In a bowl, combine the olive oil, vinegar, basil, garlic, crushed red pepper and minced rosemary. Season the dressing with salt and pepper.
Step 2
In a large bowl, combine the beans with the mackerel and onion and toss gently. Add the dressing and toss again.
Step 3
Mound 1/4 cup of salad on each toast, garnish with rosemary sprigs and serve.
Notes
Don't mix this salad too far in advance, since the acid in the vinegar will discolor the herbs and wilt the leaves.
