I got a lot of mileage from my roasted tomato marinara. It was so intense that it just got better and better when you add your favorite jarred sauce to it. The flavor varies when you do this - it's like a new marinara each time.
You can also shake things up by trying different kinds of pasta. I went to Eataly and bought different raviolis, which are best with pesto. I got interesting pastas to go with the marinara. Last night I tried spinach linguine.
I sauté heirloom tomatoes and add to sauce
Fresh home made spinach linguine from Eataly
Fresh pasta cooks in under 5 minutes and freezes really well (freeze when you get it home from the store and before you cook it)
It's so good you could have it plain
But it's even better with marinara
All it needs is a bit of parmesan
Here's the link for the marinara recipe: http://www.skinnygourmetguy.com/2011/10/marinara-with-roasted-tomatoes.html. It take a little bit of time to prepare, but once you do it freezes very well and you'll have the basis for many delicious dinners.
