Ingredients

1 shallot or small onion finely diced
4 teaspoons extra virgin olive oil
1/2 teaspoon crushed red pepper flakes
3 large garlic cloves crushed
1/4 teaspoon salt
1 rosemary sprig
2 15 oz cans cannellini beans
1/2 cup vegetable broth
1/4 cup milk
2 5 oz cans tuna in water, drained (or use plant based tuna)
1/2 teaspoon rosemary dried, crushed
4 tablespoons cheese shredded
1/4 teaspoon freshly ground pepper
1 cup potato chips crushed (about 4-5 handfuls)
1 tablespoon butter cut up

Instructions

Pre-heat the oven to 350 degrees
Sauté a shallot or small diced onion in 3 teaspoons olive oil over medium high heat.
Lower heat and add in 1/8 teaspoon salt, red pepper flakes, and crushed garlic.
After lightly cooking garlic, add in the two cans of white beans, vegetable broth, and sprig of rosemary.
Simmer for about 6-8 minutes until all of the liquid evaporates. Remove rosemary sprig.
Using a potato masher or the back of a spoon, gently smash beans to the desired consistency - leaving them as chunky or smooth as you want them.
Add in milk, both cans of tuna, and 1 teaspoon olive oil. Combine the ingredients. Using the same potato masher or spoon, gently smash the tuna. Turn off heat.
Sprinkle in grated lemon zest, pepper, 1/8 teaspoon salt, 2 tablespoons of cheese and crushed dried rosemary.
Pour into an 8x8 oven safe pan. Top with crushed potato chips, dots of butter, and the last 2 tablespoons of cheese.
Bake for 20-25 minutes, then broil on high for 2 minutes to brown the potato chips.
Squeeze on lemon juice right before serving.
