No reason to buy Bodek. Any frozen vegetable with a hechsher (I’ve even seen without a hechsher in frum stores) should be fine.
Another suggestion is that many stores offer half off on prepared foods a couple of hours before closing on erev shabbos. I know that Kosher Palace and Moisha’s do this, maybe also Kosher Corner.
I find that the roast chicken specials in frum take out stores are also a good deal- a chicken and a side for 10 dollars is a modest meal for 2.
