I found this recipe for "Nice Spinach Spaghetti Sauce" a few weeks ago and tried it as I had some fresh tomatoes & parsley and even though I didn't have fresh basil, it was still mighty tasty! It's very fresh tasting, like nothing I'd ever had till then, not the same old same old pasta sauce.
This is how I made it:
2 tsp. minced garlic (from a jar in my fridge)
1 Tbsp. dried basil (I'm sure fresh would be way better)
1 can diced tomatoes
about 1 c. frozen spinach, defrosted
1/4 - 1/2 cup chopped fresh parsley
1/4 cup of olive oil
1-2 fresh roma tomatoes
I wizzed this all up in the blender, then either warm on the stove or lightly heat in the microwave. It turns a slightly yucky color, not nice and red, but the taste more than makes up for it.
Tonight tho I didn't have the jar of tomatoes, but did have some leftover spaghetti sauce and some tomato juice from a can of diced tomatoes, didn't have olive oil so just used vegetable oil and didn't have any fresh roma tomatoes, but it still turned out pretty good, had it with homemade gnocchi; not too shabby.
