Ham and Potato Casserole (Easy and Economical!)

1 cup milk

5 pounds white potatoes, peeled and sliced

1 (12 ounce) can lite luncheon meat (such as Spam®), cut into 1/2-inch chunks

½ cup margarine, cut into pieces

2 tablespoons salt, or more to taste

Grease a heavy pot or Dutch oven.

Layer about 1/3 of the potatoes into the bottom of the prepared pot.

Spread 1/2 of the luncheon meat on top.

Sprinkle with about 1/2 of the margarine and about 1/3 of the salt. Repeat the steps once more, then layer the remaining potatoes and margarine on top. Season with salt.

Pour milk over potato mixture and cover.

Heat pot over medium-high heat until milk begins to bubble, then reduce heat to medium-low. Simmer until potatoes are tender, about 20 minutes.
