Hamburger Stew with Potatoes

Heat a large nonstick skillet over medium-high heat. Cook and stir ground beef in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease.

Transfer beef to a large pot and add water, tomato sauce, potatoes, tomatoes, onion, sazon, bouillon cubes, garlic, chili powder, cayenne pepper, bay leaf, and black pepper. Bring to a boil over medium-high heat. Reduce heat to medium-low and simmer for 10 minutes. Add frozen vegetables and continue to cook until potatoes are tender, about 10 minutes more.
