Ow, admittedly I hadn’t considered allergies. In that case I suspect you’d find something like pasta with bechamel (100 grams of chicken stir fried, 100mL of bechamel sauce, served with pasta) to be similarly affordable. Basic fried rice with stir fried chicken is also dirt cheap. Really chicken in general is the load-bearing pillar of non-vegetarian cheap cooking, though since you say “our house” I suspect you already know that.
