If it was me I would dry the tomato's and save them for later. Also take some of the dry tomato's and make tomato powder. I use it in vegan cheese and other things. As for the potato's maybe try making flour?
My favorite way to eat a potato is hasselback potato. Using a lot of garlic, onion, pepper and salt. Just writing this makes me hunger for hasselback potatoes.

Tomatoes I don't normally freeze but I do make some very concentrated pasta sauce for the freezer that I freeze in small blocks just big enough for one portion of pasta. I can also use it as a pizza sauce.
Potatoes I do end up freezing a lot of potatoes so freeze them as finished products;
Hash browns (mimicking the little triangles from the supermarket)
Gnocchi (often with squash as well)
Oven Chips (fries for you Americans :p) blanch them then spray with oil and freeze
Roast potatoes, blanched and frozen
Mashed potatoes, (plain for use in bread or anywhere else)
I freeze them all on trays and then bag up once frozen so they don't stick together and I can take out only what I need.
I have never frozen potatos, if i did, i would likely dice them for soup then freeze. Potatos dehydrate pretty well if sliced thin.
I am lazy with my tomato freezing - most are frozen whole, not even peeled. Larger ones are quartered or diced then frozen. Sometimes if i have a ton will make a lazy immersion blendered and simmered and sieved tomato sauce, especially if i have other random veggies that need to be used, and label it as "vegetable sauce".
