What are your easiest and quickest ways to squeeze an extra few hundred calories in a day?

I’m having trouble meeting my calorie intake for bulking, which is around 3100 now. Notably after like 10 PM I often realize I need 200-600 more calories (I sleep around 1-2 AM) but I’m already too lazy to make a meal. Here’s what a normal day of eating looks like for me.

Breakfast: 800cal breakfast shake. I eat this every morning. I don’t anything else. I have little appetite in the morning so this helps.

Lunch. Maybe 400-600cal of some carbs and meat.

Protein shake: 250cal, milk + whey protein.

Dinner: 400-500cal of a different carb and veges and tofu and such, typically vegetarian.

Snacks: 400cal of nuts or trail mix, 150-300cal of some random ready-to-eat frozen sausage or something that gets me to my protein goal. And fruits that are low enough in calories that I don’t count them much.

Then I have a few hundred left. Any suggestions for quick and easy? Without PB preferably lol. I’ve been relying on stuff like eggs or hash browns and such but they’re getting boring and eggs are getting pricy. I would love to stay healthy but at this point I’ll suffice for like frozen meals or snacks, like one I’ve been enjoying is frozen ravioli but I’m sick of that too.
