Mom's Spinach Squares

1lb. fresh (2 packages frozen) chopped spinach

2 1/2tbs. butter

3 eggs

1/2c. walnuts
1/4tsp. basil
1/4tsp. oregano
1/4tsp. sage

1/4c. parmesan, shredded
1/4c. sharp cheddar, shredded

2 shakes tabasco

1/4 small  onion, chopped

1/4c. green chile, chopped

black pepper

red pepper flakes

I have a confession: I can never get this recipe right. Ever. It always tastes just fine, but the texture just isn't the same as when Mom makes it.  All the same, here it is-- may you have better luck than me!
Cook and drain the spinach well (too much water will lead to something resembling gratin more than squares), then melt the butter in. Meanwhile, saute the onion. Pulse the walnuts, oregano, sage and basil until they form meal, then mix everything together.  Pour into a greased casserole dish and freeze half an hour.  Bake at 350° for 25-40 minutes, until firm with lightly golden cheese.
