Step-by-Step Cooking Instructions
Pre-Cooking Prep
-
Wash collards thoroughly and slice thinly.
-
Slice portobello mushrooms evenly.
-
Grate or slice cheese and set aside.
Cooking Method
-
Heat olive oil in a skillet over medium heat.
-
Add portobello mushrooms and cook until browned and moisture evaporates, about 5–7 minutes.
-
Add garlic (and onion if using) and cook 30 seconds.
-
Add collard greens and a pinch of salt. Cook until wilted and tender, about 3–4 minutes. Remove from heat.
-
Butter (or spread mayo on) one side of each bread slice.
-
Place bread butter-side down in a skillet. Layer cheese, vegetable mixture, more cheese, and top bread.
-
Cook over medium-low heat until golden and cheese melts, about 3–4 minutes per side.
Doneness or Texture Check
The bread should be deeply golden and crisp. Cheese should be fully melted and holding the filling together.
Resting or Final Touches
Let the sandwich rest for 1–2 minutes before slicing. This helps everything set and prevents filling from sliding out.
