Oven for Tamar and Avshalom

Avshalom, 54, and Tamar, 53, have 10 children, ages 18-34, five of whom are married. The other five live at home, among them a son with schizophrenia. Avshalom works as a teacher, while Tamar was a kindergarten assistant; currently she is unemployed because of the Corona lockdowns.
The family functions well, and their home is clean and orderly. They have never had enough money, however, and often rely on public support for food. Their furniture and appliances are mostly old and second-hand.
Avshalom suffers from diabetes, an autoimmune disease that flares up when he is under stress, as he is much of the time now. Recently, their old and heavily used oven failed. Most of the stove burners do not work either. Because Avshalom and Tamar cannot afford to buy a new one, the family has been relying on a toaster oven for cooking and reheating food. A new oven would certainly improve their quality of life.
