My grandmother used to make this budget-friendly dinner every spring. Just 4 ingredients and the meat falls right off the bone

If you prefer a little heat, use a spicy barbecue sauce or add a pinch of crushed red pepper flakes into the sauce mixture before pouring it over the ribs. For a smokier flavor, choose a hickory or mesquite-style barbecue sauce, or add a tiny splash of liquid smoke (just remember that would technically add an extra ingredient). You can swap the cola or root beer for Dr Pepper or another dark soda you have on hand; each one gives a slightly different sweetness. To make cleanup even easier, use a slow cooker liner. If you like a thicker, stickier glaze, transfer the cooked ribs to a plate and pour the sauce and onions into a saucepan; simmer on the stove for 5 to 10 minutes to reduce before spooning it back over the meat. Leftovers keep well in the fridge for up to 3 days and can be shredded and mixed with the sauce for sandwiches, baked potatoes, or quick rice bowls on busy nights.
