Spinach Tomato Cheesy Pasta

I got this recipe while watching Giada one day on the Food Network. I thought it sounded great, but not the cheapest in the world - but real quick.
It is vegetarian and healthy and yummy and quick!

1 box whole wheat fusilli pasta (spirals)
1 bag spinach - baby spinach is best
1 pint (container) cherry tomatoes - halve them
1/2 cup grated asiago cheese (in deli section, specialty cheese) - Giada used 1 cup, but 1/2 is fine)
1/2 cup grated parmesan cheese (go for the good stuff, not Kraft for spaghetti)
Olive oil
s/p

Boil water for pasta and let cook. When you put the pasta in, heat up about 1/4 cup olive oil in saute pan. Drop in spinach and let wilt down, add tomatoes, s/p. When done, take a slotted spoon to get out the pasta and put it right into spinach pan (that way some of the starchy water makes a thicker sauce with the olive oil). Add in cheeses and toss.
Serve immediately!
I just put a simple salad with it and it was yummy. Even Dad liked it and he doesn't like pasta dishes usually. Very simple and healthy with fiber, green, red, healthy fats, and calcium.
