Recipe help, what would you do?

My son is asleep, and I won't have time to run to the store to grab an additional item before I need to cook this dish. Here's the link...

I only have 14oz of the tomatoes needed, not 28oz. I do have regular tomatoes that I can chop, and I also have a tomato sauce (spaghetti sauce, basically.)

Would you just spread the bottom of the pan with some of the canned, and then top with the freshly chopped tomatoes? Or would you spread the bottom of the pan with a little plain sauce, and then top with the canned tomatoes and one or two extra chopped tomatoes?

Sorry if that makes no sense. This recipe is AWESOME. I've made it once before, but now that I'm making it for someone else and I forgot 1 ingredient...I'm worried I'll mess it up.

I think you should be good mixing the sauce with the diced tomatos.

Blanch & peel the tomatoes you have. Chop them up & mix the sauce canned & fresh all together.

That looks yummy.  

Off topic, but I so bookmarked that recipe so I can make it this week.  

Thanks!

And yes, I'd highly recommend this recipe. It's very tasty!

I'd go with this!

I think I may! Although, I've never blanched tomatoes before   I guess if I fail, I'll just use the sauce instead!

Blanching tomatoes was the easiest thing ever. I can't believe I thought that'd be complicated...thank you!
