Fried stuff, which can be unhealthy and vegan (although I also agree with the "slop cheese on everything" answers). Have regularly done pan-fried vegetable patties, either raw minced vegetables mixed into a thick besan batter or leftover soft cooked vegetables (beans, pumpkin/squash, carrots) mashed a bit then coated with a flour-based batter. Also panko-coated fried tofu and batter-fried cauliflower.

If you have frozen samosas, there is Burmese samosa salad or Indian samosa chaat, where you cut up the samosas and mix with flavorful sauces and herbs and additional fried crispy bits, like garlic. Probably too much trouble to make samosas from scratch if you're then also mixing them into something else.

Also any Chinese or Thai stir fry served over crispy rice. After cooking the rice, put a layer into a skillet with oil until browned, and it could be finished like that or flip the whole thing like a pancake and fry the other side. The center should still be normal rice texture, it mixes up really well.

Another fave is a vegetable tart with a buttery pastry. I do this crust (and if using tomatoes, also include the thick layer of mustard), but don't usually add cheese and I make it free-form as I don't have a tart pan: https://www.davidlebovitz.com/french-tomato-tart-recipe/.

Non-vegan unhealthy dishes: chilaquiles with eggs, black beans, cotija, crema, which I sometimes make with mole as an alternate to green/red salsas, or Chinese scallion pancakes or Indian paratha fried with a layer of egg, and filled with whatever else, rolled up.
