I received Laurel's Kitchen for Christmas ( Thankyou BIL Peter). Under the chapter of Heartier Dishes are Potato Poppers:
1 stalk celery diced
1/2 tablespoon oil
11/4 cup mashed potato
1 cup brown rice
1/4 cup tomato paste
1/2 teaspoon salt
1/2 cup whole grain bread crumbs
1/4 cup parmesan
Preheat oven to 350
Saute' onion and celery in oil
Combine all ingredients and form into 1 and 1/2 inch balls.
Place on greased baking sheet ad bake on top rack of oven for 20 minutes, until delicately browned. Makes 12 balls."
I did not have celery but I did have spinach. I added minced garlic and mushroom to the mixture. I doubled the recipe. This did not hurt the consistency at all. I used homemade tomato paste. This is a great way to use of left overs of rice or mash potato. The balls held together really well.
I think next time, instead of using all bread crumbs, I might add wheat germ, nutritional yeast or flax meal for added nutrition. I think you could also spice these up ala hint of Mexico by cooking down some salsa to a thick consistency; instead of tomato paste. Substitute cheddar of jack for the parmesan.
I served this with some Caribbean Black beans and a salad. ( I know, I know greens are not seasonal now but I just craved some fresh greens).
