I didn't cook it myself. But I tried.
500g tofu
400 g spinach
100 ml milk
1 shallot
zest of 1 lemon
4-5 st. l. bread crumbs
¼ h. L. ground nutmeg
2 tbsp. l. olive oil
freshly ground black pepper
salt
Peel the onion, cut into half rings. Wash the spinach, but do not dry it. Put in a deep-bottomed saucepan, simmer over low heat, covered for 3-5 minutes. Remove from heat and chop quickly, return to the stove, add onions, stir and simmer for another 3-4 minutes on the lowest heat. Season with salt and pepper, season with nutmeg to taste and let cool.
Pour bread crumbs into one bowl. In another, mix milk with lemon zest. Cut the tofu into eight equal pieces 0.7-1 cm thick. If cut thinner, it will crumble. Place spinach over four pieces of tofu, top with the other four pieces to make sandwiches, press lightly.
Heat oil in a frying pan. Dip each tofu sandwich first in milk, then roll in breadcrumbs, and then quickly fry over medium heat for a minute on each side. Serve warm.
I found a similar recipe on the Internet from Elena Laude (I tried it without the zest)
And something else. Puffs with spinach and tofu. (Puff pastry + filling) It was served with champignon sauce (finely chopped champignons stewed in cream.
All this can be easily done in a sandwich maker.
