a protein packed salad that can be a meal, or a dinner salad
Drain most of the oil from the tuna, and pull out of the jar. Flake with a fork.
Drain and rinse the cannellini beans and drain.
Mix the tuna and beans together.
Arrange the lettuce on a plate, then scoop the beans and tuna over it.
Zest the lemon, then juice. You should have 2.5-3 tbsp of lemon juice. Put in a small bowl.
Add the mustard, salt and pepper to taste, and the basil.
Drizzle in the olive oil, whisking to combine. If the dressing sits for any length of time, whisk again before using as it will separate slightly.
Drizzle the vinaigrette over the tuna and lettuce.
If you need additional vinaigrette, just keep the ration of 1:2 for the lemon juice and olive oil.
Can be doubled.
