Corn tortillas, broiled for 2 min in the toaster oven with a few old clumps of goat & cheddar cheese
Frozen spinach mixed with a handful of fresh chopped kale that was starting to wilt
The rest of some salsa mixed with 1/2 can black beans & 2 pieces leftover chopped grilled zucchini
1/2 pkt leftover pre-cooked rice from a packet
A fried egg, tomato slices, and about 6 leaves of old-but-still-good cilantro (literally) on top
Not fancy, but it was really good. And free. And utilized food that would have gone bad. You can do this too!
