Heat vegetable oil in a skillet over low heat. Stir mustard seed into hot oil; cook and stir until seeds start to crackle, about 30 seconds.

2 . Stage

Stir tomatoes into garlic mixture, increase heat to medium, and cook, stirring frequently, until the tomatoes are softened, about 10 minutes. Add water, cumin, cayenne pepper, coriander, and turmeric to tomato mixture; stir.

3 . Stage

Mix potato, bell pepper, lemon juice, and salt into tomato mixture; bring to a boil, reduce heat to medium-low, cover the skillet with a lid, and simmer until potatoes and peppers are tender, 15 to 20 minutes. Garnish with cilantro leaves.
