Pasta: it's the default "oh no it's 8:30 and I must eat right now!" food. It's fast, easy, and cheap; on the other hand, it's usually not exactly the most protein-ridden food available. So it's a good thing I stashed a bunch of this premade pesto & ricotta tortellini the other day.
For the sauce, I just sautéed as many vegetables as I could fit in the pan--shallot, garlic, jalapeño, mushroom, grape tomato, zucchini, orange bell pepper--with olive oil, basil, salt & pepper, and a big handful of fresh parsley. Dinner accomplished!
