This hardly constitutes a recipe since it is mostly dump and stir but I must share it here because I love it so much. The tangy vinegar mixed with spicy onions and creamy lentils makes my perfect in-a-rush lunch. I usually just eat it right out of the bowl but it is also nice on a bed of red leaf lettuce.
One can lentils, rinsed and drained
1 can tuna, packed in olive oil, undrained
1/4 onion, diced
1/4 cup red wine vinegar
In a medium mixing bowl, stir all ingredients together.
I usually add more vinegar as it is quickly soaked up by the lentils.
