Minimal-Ingredient Meatloaf?

[wefoughtharder]

Is it possible to make a meatloaf with no nuts and no breadcrumbs?  Every recipe I've seen in the memories seems to call for some kind of ground nut, which i don't have access to right now.  I do have:

1 can of Worthington Vegetarian Burger
Quick cooking oats
About 1 cup of red lentils, and a small amount of brown lentils
Vital wheat gluten flour
Instant brown rice
Vegetable broth
Various herbs and spices

I know that there is that vegan meatloaf generator online, but it looks as if ground nuts are a requirement and I don't want to waste any ingredients on something that's going to come out gross.

Thanks in advance!
