Cook rice according to package directions until fluffy and tender. Keep hot until ready to assemble bowls.
While rice cooks, heat a large skillet over medium-high heat. Add ground beef and break into small crumbles with a spatula.
Cook beef for 5-7 minutes, stirring occasionally, until completely browned with no pink remaining.
Drain excess fat from the skillet, leaving just enough to keep the meat moist.
Return skillet to heat and sprinkle taco seasoning evenly over the beef. Pour in water and stir to combine.
Simmer for 3-5 minutes until the liquid reduces into a thick sauce coating the beef. Add a splash more water if it looks too dry.
While beef simmers, rinse and drain black beans. Drain or thaw corn kernels. Warm both briefly in the microwave for 30-60 seconds.
Chop fresh cilantro and prepare salsa.
To assemble bowls, divide hot rice among four serving bowls as the base layer.
Top each bowl with seasoned beef, black beans, and corn arranged in separate sections.
Sprinkle shredded cheddar cheese over the warm ingredients, allowing it to begin melting.
Finish with salsa and fresh cilantro. Serve immediately with lime wedges for squeezing.
