That's like a sloppy joe.
I've been doing this new thing lately.
Take one large tupperware container.
Put in lettuce, spinach (raw), onions, tomatoes, shredded mexican cheese, and dressing (I prefer vinegrette).
Place container, shake liberally.
Top with brown rice, black beans, salsa, and sour cream.
The result is a satisfying, yet healthy vegetarian taco salad of sorts.
