This thread has just made me laugh because we’ve all been there. Sorry you’re feeling crappy Hope you feel better today .
Far too late, I know, but I would have boiled up some pasta shapes, throw in with the mince, covering with cheese sauce and baked. For the potatoes, I’d have crushed them slightly if new pots with garlic and butter and fried them in until crispy outside, keep warm in the oven. If regular potatoes, add butter and garlic and mash, and fry off dollops into crispy inside patties, or just sauté them in butter and garlic.
or used the potatoes as layers instead of pasta.
or cook some rice, add spice and tin of beans (kidney or black or none, not baked) to the ragu and made chilli, then frozen cheese sauce. Do potatoes as above or sauté with some spices.
or used tortilla wraps (if you had any in) as the lasagna sheets and keep everything else the same as you intended. (This also is good if you add spice (fajita spice) and is a sort of tortilla lasagna Mary berry recipe).
or if you really wanted/could be arsed, make mash, make arrancini type balls using the potato (instead of rice), fried it off and added cheese sauce on top and grill to get colour.
We were supposed to have roast chicken leftover pie today, but I forgot to buy pastry, and couldn’t be arsed to make it. We had roast chicken and veg stirfry with rice! I have leftover roasties I’ll sauté with another meal!
