I've never made this recipe with frozen vegetables, but I'm betting it'd still be very tasty, so that's also an option and a huge time saver. With those, this meal would be ready in about the time it takes to cook the pasta.
But whether using fresh produce or a frozen blend of vegetables, be sure to shop the sales. The same approach applies to the expensive ingredients like the fettuccine or feta cheese called for in this meal. You will never catch me paying full price for these pricey items, unless it’s a very special occasion meal.
But if I’m planning my menus for the week ahead using the store flyer (as I always am) and notice that they’re on sale, I might make a point of putting this recipe, or others that might call for them, such as my Pasta with Spinach, Tomato, and Feta, on my meal plan for the coming 7 days.
