Break apart the ground beef in a big skillet and cook it over medium-high heat until it browns completely. Drain any grease. Toss in the diced bell peppers, onions, taco seasoning, and about 1/2 cup of water. Mix well and simmer for 10 minutes until the veggies soften up. Turn off the heat and let it sit.

Pop the dish into the oven for 30 minutes. Once baked, let it rest for around 7-10 minutes to firm up a bit before you dig in. Add a sprinkle of fresh parsley to make it look extra nice, if you’d like.
