Wash green beans. Trim both ends and cut all in half, you can do this in bunches. BUT: If you wanna go old school put them in a bowl, grab a couple empty bowls and snap those beans by hand, putting the ends in one bowl and snapped beans in the other.

Trim onion ends, remove skin, halve pole to pole, then cut each half into thirds from pole to pole.

Place green beans in a 2 quart pot. Add water, salt, and liquid smoke. Stir to combine. Lay onion sections on top. The water won't cover everything and that's okay.

Place lid on pot. Bring to a boil over medium high heat. Reduce heat to medium/medium-low and cook covered at a hard simmer until very tender, generally 1.5 - 2 hrs. Stir occasionally.
