While your potatoes cook, prep the broccoli-bacon mixture: Heat the oil in a large frying pan on medium-high heat. Add the broccoli and bacon and cook, stirring, until the broccoli turns bright green, about 5 minutes. You can keep cooking until the broccoli blackens a bit, if you like, or stop right when it’s just done. This is up to your tastes!
Divide the potato pieces between 4 bowls, then divide the broccoli-bacon mixture between them. Top each bowl with 2 tablespoons of queso, ¼ of the green onions, and ¼ cup diced tomato.
