Quick disclaimer: Your husband will notice the lack of meat. Your kids will notice the abundance of onions and vegetables. You will notice that these don't account for a day's worth of Weight Watchers Points (probably).
I based this recipe on one I found on Self.com and it is AMAZING. The picture is from their website, not my kitchen. You'll notice they included tomatoes, which I'm not a fan of, so I left out. They also didn't toast their corn and chopped the zucchini much finer that I like. Honestly, it's plenty filling and flavorful without meat, but you could easily add thinly sliced steak, if you can't go meatless for one meal. The recipe in the link says it feeds 4, but since I live alone, the recipe I wrote below is enough for my dinner and enough leftovers for lunch the next day.
1 garlic clove, minced
1 medium onion, chopped
1 zucchini, course chopped
1/2 cup black beans, drained and rinsed
1/2 cup canned corn, drained
Oregano, salt and pepper, to taste
Corn or Flour Tortillas
Heat olive oil, add onions and cook until caramelized. Add garlic and zucchini and cook until the zucchini is tender. Add corn and cook, stirring occasionally until toasted. Add black beans, oregano, salt and pepper, and cook until everything is warm. Heat tortillas and assemble with remaining ingredients. I'm going to assume you all know how to do that part...
