How Can I Solve My Tofu Dilemma?

I thought I bought the extra firm tofu which I usually slice, marinate and then stir fry with veg. However, I accidentally bought the kind that is quite soft and cannot be sliced. I had the marinade already prepared so I poured it over the tofu blob (ginger, garlic, chillies, onions, soy sauce). But now, I don’t know what to do with it. Suggestions please!
