Sweet & sour meatballs - easy to do in crockpot or oven-baked casserole: 2 bags turkey or beef meatballs (about 48 total). Make sure they are not Swedish or Italian. Add 1 large bottle of chili sauce and 2 small jars of currant jelly (I mix them over a saucepan or in the microwave first and stir to blend), then dump over the meatballs. Heat until meatballs are hot - probably 6 hours in crockpot, 40 minutes in oven, stirring once.
Artichoke cheese dip - 1 can artichokes (not marinated), thoroughly drained and liquid squeezed out, 1 cup good mayonnaise, 1 cup shredded Parmesan cheese (use the bagged stuff from the refrigerator section). For a big crowd, double these quantities. Throw it all in the food processor if you have one, otherwise chop the artichokes and mix in the rest. Add pepper or seasoned pepper to taste, put the whole thing in a baking dish or crock. Sprinkle a little extra pepper on the top. Bake 350 about 30-35 minutes until the top starts to brown and bubble. Serve with party pumpernickel, party rye, or any substantial cracker. Put a couple of appetizers knives or a couple of spoons in there for spreading. You can make this ahead except for the baking party.
Cheese puffs - easy, make-ahead recipe. Take one package of good English muffins, halve them, and toast lightly. You'll have 12 halves. Make a mix of cheddar or Mexican-type cheese (about 1 or 1.25 cups), about 1/2 cup of good mayo, and mix into a paste. Quantities don't 't matter that much so just wing it. If desired, mix in a can of crabmeat. Spread the cheese mixture onto the muffin halves, then take a sharp knife and cut the circles into 4 quarters (like cutting a pizza). You'll have 48 little wedges. Put them on a baking sheet - you can refrigerate or freeze at this point. I cover with foil or plastic and stick a few toothpicks into the muffins to hold the wrap off the cheese. At serving time, put in a 350 degree oven or even under the broiler until the cheese is bubbling and browning. (15 minutes or so in a regular oven if you are cooking other things, less time if alone and under the broiler. These are best if passed to guests but you can keep them not on a heating tray. People will think you fussed.
